Question

1pt wavelength is a measure of the horizontal distance between _______.

a. two wave crests

b. a waves crest and trough

c. a waves crest and the ocean surface

d. any two water molecules in the same wave

Explanation:

Wavelength in wave physics is defined as the horizontal distance between two consecutive corresponding points on a wave, such as two wave crests (or two wave troughs). Option B is the distance related to wave height (vertical distance between crest and trough). Option C is not a standard definition related to wavelength. Option D is incorrect as water molecules in a wave move in a circular motion and the wavelength is not about the distance between any two water molecules. So the correct answer is A.

Answer:

A. two wave crests
