When light moves from one medium to another it can be Refraction
Explanation:
Refraction is the term used to define light movement travelling from one medium to another. Light waves are propagated, will cross the boundary and their direction is also changed during the process of refraction.
Velocity is also induced in the light which keeps changing during its propagation through mediums. There are other phenomenons of light like reflection, interference, diffraction which are slightly different from each other and hence proper understanding is required to differentiate between them.

6.
Answer:
45 meters
Explanation:
notice that is you multiply the time with the speed the units cancel to get distance.
therefore
distance=velocity(time)
distance=(3)15
distance =45 meters

Answer:
1. the speed is constant
2. the average speed is .5 m/s
Explanation:
I have attached a graph of the data in excel.
from excel i got the equation of the line to be y=.5x with y being distance and x being time.
the function is a position function so if you take the derivative of it you get the velocity which is .5.
since the derivative is a constant the the speed does not change and the average velocity is the derivative.
