Question

what is meant by no refraction of light???​

Answer 1

Answer:

it means that that a light has no refraction

Explanation:

Refraction is the bending of a wave when it enters a medium where its speed is different. The refraction of light when it passes from a fast medium to a slow medium bends the light ray toward the normal to the boundary between the two media. ... Refraction is responsible for image formation by lenses and the eye.

Answer 2

The turning or bending of any wave, such as a light or sound wave, when it passes from one medium into another of different density. The ability of the eye to bend light so that an image is focused on the retina.
