Question

i need help on this so i can pass my grades are terrible i need help someone please help me like rn!! Hypothesis: If light travels at different speeds in different mediums, then the light will (bend or stay the same) at the point where it enters a new medium.
Type your hypothesis below, use complete sentences, and use the above sentence as a guide.

Answer 1

read up on Snell's law.

Answer 2

If it hits the surface at an angle other than 90 degrees then its propagation angle will change.
If the speed is slower than in the earlier material, then the wave will bend down toward perpendicular to the surface because the first part of the wave front slows down before the points on that wave further from the surface hit it.
The result is consolidated in a formula called "Snell's Law"
n1 sin T1 = n2 sin T2
where n is the refractive index and T is the ray angle measured from perpendicular
