Physics Experiments MCQ Quiz Questions With Answers

Snell's law experiment is used to determine the refractive index of a material. By measuring the angles of incidence and refraction when light passes from one medium to another, the refractive index can be calculated using Snell's law.

Rutherford's gold foil experiment is used to investigate the properties of atomic nuclei. By bombarding a thin gold foil with alpha particles, Rutherford observed scattering angles that led him to propose the existence of a dense atomic nucleus.

Pascal's law experiment is used to demonstrate the concept of pressure in fluids. According to Pascal's law, the pressure applied to a fluid in a confined space is transmitted equally in all directions.

The ballistic pendulum experiment is used to determine the acceleration due to gravity. By measuring the height and range of a projectile launched into a pendulum, the acceleration due to gravity can be calculated.

The Millikan oil-drop experiment is used to determine the charge of an electron. By measuring the motion of charged oil droplets under the influence of an electric field, the charge of an electron can be calculated.

The double-slit experiment proves the wave-particle duality of light. When light passes through two closely spaced slits, it behaves both as a wave, exhibiting interference patterns, and as a particle, forming discrete spots on a screen.

The method of mixtures experiment is used to measure the specific heat capacity of a substance. By mixing a known amount of substance at a known temperature with a known amount of water at a different temperature and observing the final equilibrium temperature, the specific heat capacity can be calculated.

The Cavendish experiment determines the gravity constant. By measuring the torsion caused by the gravitational force between two masses, the gravitational constant can be calculated.

The Michelson-Morley experiment tests the speed of light in vacuum. It aimed to determine the Earth's motion through the hypothetical luminiferous ether by measuring the interference of two light beams traveling perpendicular to each other.

The photoelectric effect experiment investigates the charge of an electron. By shining light on a metal surface and measuring the emitted current, the charge of an electron can be determined.
