Question

1. Which wave refracts?

A an ocean wave hitting a break wall
B a wave going around an obstruction
C an ocean wave approaching the shore at an angle
D a wave that ripples in a fountain

Answer 1

Answer: I believe the answer is D. A wave that ripples in a fountain.

Let me know if I'm wrong, thank you! Hope this helps too! :-)

Answer 2

C. an ocean wave approaching the shore at an angle

Step-by-step explanation:

In wave physics we can say that one of the main phenomena involving two-dimensional waves is refraction. The refraction of a wave occurs on the liquid surface, when a wave passes from one medium of propagation to another, that is, it passes from a region of greater depth to another region of less depth, or the other way around. In this case, we can conclude that the option that best exemplifies a situation where the refraction of a wave occurs is "an ocean wave approaching the shore at an angle".

In refraction, the frequency of a wave is the frequency of the generating source, that is, it remains constant. The speed and the wavelength are directly proportional, this can be verified through the equation: v = λf. The deviation in the direction of propagation of a wave will only occur if it falls on the separation surface between the media with an inclination, that is, if it falls obliquely.
