Yellow light is incident upon a medium from air at an angle of 45.0°. The light bends toward the normal and refracts at 28.0°. W
hat is the index of refraction of yellow light in this medium? DOK 2
a. 1.61
b. 0.66
c. 1.51
d. 1.00

i would say C. This link should ex plain it well https://www.britannica.com/science/refractive-index
Answer:
c. 1.51
Explanation:
i = angle of incidence made by yellow light at air-medium interface = 45.0°
r = angle of refraction made by yellow light at air-medium interface = 28.0°
n₁ = index of refraction of air = 1
n₂ = index of refraction of medium = ?
Using Snell's law air-medium interface
n₁ Sini = n₂ Sinr
1 Sin45 = n₂ Sin28
n₂ = 1.51
So the correct choice is
c. 1.51

Answer: A. All of the answers are correct.
Answer:
Explanation:
The question relates to time of flight of a projectile .
Time of flight = 2 u sinθ / g
u is speed of projectile , θ is angle of projectile
= 2 x 48.5 sin42 / 9.8
= 6.6 seconds .
Maximum height attained
= u² sin²θ / g
= 48.5² sin²42 / 9.8
= 107.47 m .
