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

vlada-n [284]

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 .
