Match the terms to the correct descriptions. question 1 options:
light behavior in which light goes through a medium and bends, going in a different direction.
light behavior in which light waves bounce off a medium and goes in a different direction.
a surface shaped in such a way that the center curves inward like this:
a surface shaped in such a way that the center curves outward like this:
1. reflection
2. refraction
3. concave
4.convex

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.

the answer would be c. motion and direction

i hope this : )
