Question

do the lens reflect the light​

Answer 1

Explanation:

Tjhe Fresnel equations tell you how much light will be reflected from the surface of a lens. The amount of light reflected depends on the index of refraction of the glass, and on the angle of the incoming light. ... There is nothing inherent in a Fresnel lens that changes this 4% reflectance.

Answer 2

Answer:

Lenses serve to refract light at each boundary. As a ray of light enters a lens, it is refracted; and as the same ray of light exits the lens, it is refracted again. The net effect of the refraction of light at these two boundaries is that the light ray has changed directions.
