Question

Match the terms to the correct descriptions. Question 1 options:

Answer 1

Answer: 1. Reflection: light behavior in which light waves bounce off a medium and goes in a different direction.

Refraction: light behavior in which light goes through a medium and bends, going in a different direction.

Convex: a surface shaped in such a way that the center curves outward

Concave: a surface shaped in such a way that the center curves inward

Explanation: When light bounces on a surface instead of being absorbed, then it goes in a different direction and that is called reflection while in refraction the light bends at the junction of two mediums because of varying densities.

A concave surface is one that curves inwards at the center like the interior of a circle while a convex surface is one that curves outwards like the outer part of  a circle.

Answer 2

1) Refraction
2)Reflection
3)Concave
4)Convex

I took the test and got this right so you can believe me :)
Hope this helps
