Important Topics for HC Verma Concepts of Physics Part-1 Solutions Chapter 21: Speed of Light
Speed of Light
A technique of calculating the speed of light is to measure the time required for light to travel to a mirror at an identified distance and back. Calculating the distance between the wheel and the mirror, the number of teeth on the wheel and the rate of rotation, the speed of light can be calculated.
In physics, angular velocity mentions how fast a body rotates or revolves relative to another point, i.e. how fast the angular position or alignment of a body changes with time. There are two types of angular velocity including orbital angular velocity and spin angular velocity.
In optics, the refractive index or index of refraction of a substance is a dimensionless number that defines how fast light travels through the substance. It is described as where c is the speed of light in vacuum and v is the phase velocity of light in the medium.
Distance is a numerical dimension of how far apart bodies or points are. In physics or everyday usage, the distance may denote a physical length or an approximation based on other criteria. In most cases, “distance from A to B” is exchangeable with “distance from B to A”.
The Fizeau experiment was released out by Hippolyte Fizeau in 1851 to calculate the relative speeds of light in moving water. Fizeau used a distinct interferometer arrangement to calculate the effect of movement of a medium upon the speed of light.
The speed of light was calculated using the Foucault method of reflecting a ray of light from a rotating mirror to a fixed mirror and back producing two distinct reflected beams with an angular displacement that is connected to the time that was essential for the light beam to travel a specified distance to the fixed mirror.
