Which image illustrates the bouncing of a light wave off of a surface? A
B
с
D
A. A
B. B
C. C

A

Explanation:

The light Bounces off because it is reflecting off glass or anything else

the diagram which shows forces as either balanced = same speed or unbalanced = accelerarting

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .
