Question

Which two options are examples of waves refracting?


A.
An object appearing broken when partly seen through water

B.
A voice echo

C.
Your image in a mirror

D.
Light bending as it travels through glass

Answer 1

Answer:

a

Explanation:

b is a refraction

c is a image

d is refraction but not waves

Answer 2

Answer:

The correct answers to the problem are found to be options (a) object appearing broken when seen through water and (d) Light's bending as it  travels by glass.

Explanation:

• In physics,Refraction is the change in direction of a wave passing from one medium to another caused by a change in velocity. For example, waves move faster in deep water than in shallow water.
• When an ocean wave approaches the beach at an angle, the part  farther from the beach travels faster than the part closer to it, so the wave oscillates until it travels perpendicular to the shoreline.
• Sound waves travel faster in warm air than in cold air. At night,  the surface air of the lake cools, and sounds traveling upward are refracted downward by the  still warm upper air. As a result, sounds such as voices and music are much more audible above the water at night than during the day.
