Question

True or false the refraction of a wave is how many wavelengths pass a fixed point each second

Answer 1

False. That description fits the wave's 'frequency'. 
It has nothing to do with refraction.

Answer 2

Answer:

False

Explanation:

- Refraction is the phenomenon that occurs when a light wave crosses the interface between two different mediums. Because of the different index of refraction of the two mediums (also called optical density), the speed of light in the two mediums is different, so the light changes direction.

- The definition described in the text of this problem, instead, is the definition of frequency. In fact, frequency of a wave is defined as the number of complete cycles (or of complete wavelengths) that pass a fixed point each second.
