Question

reflection is phenomenon in which speed of light changes in different media​

Answer 1

False

Refraction is the phenomenon in which speed of light changes in different media

Answer 2

Reflection is when light (or other forms of electromagnetic radiation) waves collide with a surface or other boundary that does not absorb the energy of the radiation, the waves bounce away from the surface.

Explanation:

The given statement is False, because

The direction of a light ray changes when it strikes the surface separating two media. The refraction of light is the name for this phenomenon.

• In a vacuum, the speed of light is greatest. Light moves at a slower rate in any medium.
• The direction of light changes as a result of this at the interface of two distinct media.
• The incident light's frequency remains constant, but its speed and wavelength fluctuate. When a light beam enters a denser media, it bends closer to the normal, whereas it shifts away from the normal in a lighter medium.
