Which phenomenon causes an object to appear bent from above the surface of one medium to below the surface of another medium? A)
vazorg [7]

Answer:

Option (D)

Explanation:

Refraction is defined as the phenomenon where the light changes its course of path while travelling from one type of medium to another. This also affects the speed of the light. This process results in the formation of images by the human eyes and lenses.

This process appears to be bending of light. When a light passes from a lighter to a denser medium, it gets bend towards the normal. And when the light passes from a denser to a lighter medium then it gets bend away from the normal.

Thus, the correct answer is option (D).

In the qualifying round of the 50-yd freestyle in the sectional swimming championship, Dugan got an early lead by finishing the
Nata [24]

Answer:

v = 0

Explanation:

Given that,

Total distance is 50 yards

Dugan got an early lead by finishing the first 25.00 yd in 10.01 seconds

Dugan finished the return leg (25.00 yd distance) in 10.22 seconds.

We need to find Dugan's average velocity for the entire race. As he returns at the initial position. As a result, the net displacement is equal to 0. So,

Average velocity = net displacement/time

v = 0

Hence, his average velocity for the entire race is 0.

A light beam in glass (n = 1.5) reaches an air-glass interface, at an angle of 60 degrees from the surface. What is the angle of
tester [92]

Answer:

θ₂ = 35.26°

Explanation:

given,

refractive index of air, n₁ = 1

refractive index of glass, n₂ = 1.5

angle of incidence, θ₁ = 60°

angle of refracted light, θ₂ = ?

using Snell's Law

n₁ sin θ₁ = n₂ sin θ₂

1 x sin 60° = 1.5 sin θ₂

sin θ₂ = 0.577

θ₂ = sin⁻¹(0.577)

θ₂ = 35.26°

Hence, the refracted light is equal to  θ₂ = 35.26°
