A ray of light traveling in air is incident on the flat surface of a piece of glass at an angle of 65.9° with respect to the nor

stich3 [128]

Answer:

$n_{glass}$ = 1.6

Explanation:

$\theta _{i}$ = Angle of incidence = 65.9°

$\theta _{r}$ = Angle of refraction = 34.8°

$n_{air}$ = Index of refraction of air = 1

$n_{glass}$ = Index of refraction of glass = ?

Using Snell's law

$n_{air}$ Sin $\theta _{i}$ = $n_{glass}$ $\theta _{r}$

(1) Sin65.9 = $n_{glass}$ Sin34.8

$n_{glass}$ = 1.6

Which of the following contributes to the phases of the Moon as seen from Earth?

balandron [24]

Answer: Varying amounts of the Moon's lit surface being visible from Earth.

Explanation:

Phases of the moon can be defined as the different shapes of the moon visible from the Earth. This happens because sun lits up the face of moon and due to different position of moon in the orbit around earth, varying portion of the lit surface of the moon is visible from Earth. Refer to the diagram below:
