## Investigatory Project in Physics for Class 11 CBSE Students

Physics is a fascinating subject that explores the nature of matter and energy, and how they interact with each other. Physics also helps us understand the world around us, from the smallest atoms to the largest galaxies. Physics is not only a theoretical subject, but also a practical one that involves experiments and observations. In fact, many of the discoveries and inventions in physics were made by conducting experiments and testing hypotheses.

One of the ways to learn physics better is to do an investigatory project, which is a type of research project that involves investigating a specific problem or phenomenon using scientific methods. An investigatory project can help you develop your skills in observation, measurement, analysis, and communication. It can also spark your curiosity and creativity, and make you appreciate the beauty and wonder of physics.

If you are a class 11 CBSE student who is looking for some ideas for an investigatory project in physics, then you have come to the right place. In this article, we will provide you with a list of some interesting and innovative physics projects that you can try out. These projects are based on the topics covered in the class 11 physics syllabus, such as mechanics, thermodynamics, waves, optics, electricity, and magnetism. You can download the PDF files of these projects from the links provided below.

## List of Investigatory Projects in Physics for Class 11 CBSE Students

• To Study and Determine the Density of Solids: In this project, you will learn how to measure the density of different solid objects using a spring balance and a measuring cylinder. You will also learn how to calculate the density using the formula D = M/V, where D is the density, M is the mass, and V is the volume. You will compare the densities of different materials and analyze the factors that affect them.

• To Study of the Parallelogram Law of Vectors: In this project, you will learn how to add two vectors using the parallelogram method. You will use a force table to create two forces acting at an angle on a ring. You will measure the magnitude and direction of the resultant force using a spring balance and a protractor. You will verify that the resultant force is equal to the diagonal of the parallelogram formed by the two forces.

• To Study of Pascal's Law and its Applications: In this project, you will learn about Pascal's law, which states that the pressure exerted by a fluid at any point in a closed container is equal in all directions. You will demonstrate this law using a syringe filled with water and connected to three tubes with balloons at their ends. You will observe how applying pressure on one end of the syringe affects the balloons at the other ends. You will also learn about some applications of Pascal's law, such as hydraulic brakes and lifts.

• To Study of the Zeroth Law of Thermodynamics: In this project, you will learn about the zeroth law of thermodynamics, which states that if two systems are in thermal equilibrium with a third system, then they are also in thermal equilibrium with each other. You will demonstrate this law using three thermometers placed in three beakers containing water at different temperatures. You will observe how the temperatures of the water change until they reach equilibrium.

• To Study and Investigate the Motion of a Pendulum: In this project, you will learn about the motion of a simple pendulum, which is a mass attached to a string that swings back and forth under the influence of gravity. You will measure the time period and frequency of the pendulum using a stopwatch. You will also investigate how changing the length of the string, mass of the bob, or angle of displacement affects the motion of the pendulum.

• To Study of the Equilibrium of Concurrent Forces: In this project, you will learn about the concept of equilibrium, which means that there is no net force acting on an object or system. You will use a force board to create three concurrent forces acting on a ring at different angles. You will adjust the magnitude and direction of these forces until they balance each other and bring the ring to equilibrium.

• To Study and Construct a Circuit of a Clap Switch: In this project, you will learn how to make a clap switch, which is a device that can turn on or off an electrical appliance by clapping your hands. You will use a microphone, an amplifier circuit, a relay switch, and an LED bulb to construct your clap switch. You will test your clap switch by clapping your hands and observing the LED bulb.

• To Study the Hooke's Law, Stress-Strain Relationship: In this project, you will learn about the Hooke's law, which states that the force applied on a spring is directly proportional to the extension or compression of the spring. You will also learn about the stress-strain relationship, which describes how a material deforms under an applied force. You will use a spring balance, a meter scale, and different weights to measure the extension and force of a spring. You will plot a graph of force versus extension and calculate the spring constant and Young's modulus of the spring.

• To Study the Physics Concept of Self Inductance of a Coil: In this project, you will learn about the concept of self inductance, which is the property of a coil that causes it to oppose any change in the current flowing through it. You will use a solenoid, an AC source, an ammeter, and a rheostat to measure the self inductance of a coil. You will vary the current and observe how it affects the induced voltage across the coil.

• To Study the Phenomenon of Tangent Galvanometer: In this project, you will learn about the phenomenon of tangent galvanometer, which is a device that can measure the magnitude and direction of a magnetic field. You will use a compass needle, a circular coil, a battery, a rheostat, and a key to construct your tangent galvanometer. You will measure the deflection of the compass needle and calculate the magnetic field strength using the formula B = kI tan θ, where B is the magnetic field, k is a constant, I is the current, and θ is the angle of deflection.

• To Study the Reflection and Refraction of Light: In this project, you will learn about the reflection and refraction of light, which are the phenomena that occur when light rays bounce off or bend through different media. You will use a plane mirror, a concave mirror, a convex lens, a glass slab, a ray box, and a protractor to perform various experiments with light. You will measure the angles of incidence and reflection, and the angles of incidence and refraction. You will also verify the laws of reflection and refraction, and calculate the refractive index of glass.

• To Study the Doppler Effect in Sound: In this project, you will learn about the Doppler effect in sound, which is the change in the frequency and pitch of a sound wave due to the relative motion of the source and the observer. You will use a tuning fork, a rubber tube, a funnel, and a smartphone to demonstrate the Doppler effect in sound. You will record the sound of the tuning fork as you move it closer or away from the funnel. You will analyze the sound waves using an app on your smartphone and observe how the frequency and pitch change.

• To Study and Construct a Simple Electric Motor: In this project, you will learn how to make a simple electric motor, which is a device that converts electrical energy into mechanical energy. You will use a battery, a coil of wire, two magnets, two paper clips, and a piece of sandpaper to construct your electric motor. You will connect the battery to the coil and place it between the magnets. You will observe how the coil rotates due to the interaction of the electric current and the magnetic field.

• To Study the Resonance of a Closed Air Column: In this project, you will learn about the resonance of a closed air column, which is the phenomenon that occurs when a sound wave of a certain frequency matches the natural frequency of the air column and produces a loud sound. You will use a resonance tube, a tuning fork, a beaker, and a ruler to measure the length of the air column at different frequencies.
