Answer:
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.
<span>Discuss the relationship between electric and magnetic fields. How are they related?</span>
The magnetic field is related to the electric field in such a way that magnetic fields moves perpendicular the electric field. This relationship exists between a magnetic field and an electric field is a consequence of associating elementary particles.

Answer:
20.7 billion = 20.7E9 converting to units of 10
20.7E9 km = 20.7E12 m
t = S /v = 20.7E12 m / 3.0E8 m/s = 6.9E4 s = 69000 s
69000 s = 1150 min = 19.2 hrs
