Which describes refraction? * 10 points

O

Refracted rays travel through a boundary into a new medium.

O

The angle of incidence is the same for angle of refraction

Refracted rays change direction and go back to the original medium

Refracted rays travel through a boundary into a new medium.

Explanation:

Refracted rays travel through a boundary into a new medium. is only true for refraction.

The angle of incidence is the same for angle of refraction, is not true for refraction. Refraction follows Snell's law, states that ratio of the sine of the angle of refraction and the sine of the angle of incidence is always constant and equivalent to the ratio of phase velocities of the two mediums it is passing through.

Refracted rays change direction and go back to the original medium is false for refraction however, it is true for reflection.

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
