Is there something specific about "wavelength" that you do not understand? Do you have a problem to solve?

Answer 3

Okay, wavelength is defined as the distance between two consecutive crests.
Frequency is defined as the number of cycles per unit time.

I'll do A, and let you do B:

Wave A:
The distance from one crest to the next crest is equal to 1 m. So the wavelength is 1 m.
In 1 second, 1 full wave passes. So the frequency is 1 cycle per second, or 1 Hz.
