Question

What is refraction? Which property we use to deal with? Is it a
transparency or opacity?​

Answer 1

Answer:

refraction is the bending of light rays when it passes from one transparent medium to another transparent medium due to the change in the speed of light upon entering a new medium.

Answer 2

Answer:

transparency

Explanation:

What are the applications of refraction?

This bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms and rainbows. Even our eyes depend upon this bending of light
