Question

wavelength is:
a. the noise floor acceptable in recording.
b. the distance between two identical points on a wave.
c. the number of waves in a certain amount of time.
d. the distance between the top or bottom of a wave and the center of the wave.

Explanation:

By definition, wavelength is the spatial period of a wave, i.e., the distance between two consecutive points that are in - phase (identical points) on a wave. Option A refers to noise - floor concept, option C is the definition of frequency, and option D is the amplitude of a wave.

Answer:

B. the distance between two identical points on a wave.
