Question

Assertion (A) : Light does not travel in the same direction in all the media.Reason (R) : The speed of light does not change as it enters from one transparent medium to another​

Answer 1

Answer:

a answer is always right now

Answer 2

Both assertions are true and reason are false, and the explanation to the following is given below.

• Light does not travel in the same direction in all the media. It happens due to refraction. When light travels from one media to another having different optical densities, the direction of propagation of light changes.
• When light travels from one medium to another, then the speed of light changes. This happens because of a change of refractive index of the medium in which light travels.
• The frequency of light remains the same, whereas speed as well as the wavelength of light changes.
• The speed of light in a medium is the product of the refractive index and speed of light in air.
• v = μc ( v is the speed of light in medium, c is the speed of light in air, and μ is the refractive index of the medium)
• Therefore, both assertion is true and reason are false, but the assertion is not the correct explanation of the reason.
