Answer:
The index refraction of the unknown material is 1.08
Explanation:
Light has characteristics of a wave. When light travels or propagates through two media with different index of refraction, the light will bend or will change its speed.
Using Snells' law which is stated mathematically as:
n1Sintheta1 = n2Sinthetha2
Given:
n1 = 1.17
Theta1 = 40.1° = angle of incidence
Theta2 = 36.3° = angle of refraction
n2 = unknown
Substituting into the equation
n1Sin40.1 = 1.17Sin36.3°
0.6441n1 = 0.6937
n1 = 0.6937/0.6441
n1 = 1.08
Answer: option c: It orbits beyond the Earth's atmosphere to avoid scattering of light.
Explanation:
Hubble space telescope orbits Earth and sends images of distant objects. The images formed by Hubble are better than the optical telescopes used on land. This is because the Hubble telescope is a space telescope. Light from the distant objects when reaches the land telescopes transmits through atmosphere, where scattering occurs. Some the light rays bounce back. This is avoided by the space telescope Hubble.
