A beam of light is reflected by a rotating mirror onto a fixed mirror, which sends it back to the rotating mirror which it is again reflected making an angle of 18° with its original direction. The distance between the two mirrors is 10 km and the rotating mirror is making 375 revolutions per second. calculate the velocity of light.
The beam of light after the reflection at a plane mirror, rotating 2000 times per minute, passes to a distant reflector. it returns to the rotating mirror from which it is reflected to make an angle of 1° with its original direction. If the distance between the mirror is 6250 m, calculate the velocity of the light.
A plane mirror is placed at the center of a concave mirror having a radius of curvature of 40 m. The plane mirror rotates at the speed of 2600 revolutions per second. Calculate the angle between ray incidents on the plane mirror and then reflected from it after the light has traveled to the concave mirror and back to the plane mirror. Given, speed of the light is 3 x 10^8 m/s.
In Michelson's rotating prism method, the distance between the rotating prism and the distant mirror is 45 km. A minimum speed of 416.7 revolutions per second is needed to view the source in the same position as when the prism is at rest. Calculate the speed of light.
Describe Michelson's method for determining the speed of light.
What are the advantages of Michelson's Method for finding the speed of the light?
Describe the Foucault's method of determining the speed of the light.
Which parameter of light does not change on refraction?
If light travels from one medium to another, its velocity changes. Is it due to the change in frequency or wavelength? Explain.
