Break Down the Problem

1. Identify the terms related to wave properties.
2. Clarify what is meant by "depth of crest" in the context of wave terminology.

Relevant Concepts

1. Wavelength (A): The distance between successive crests (or troughs) of a wave.
2. Frequency (B): The number of cycles of the wave that pass a point in one second.
3. Amplitude (C): The maximum height of the crest (or depth of the trough) from the rest position, which is commonly referred to as the depth of the crest.
4. Velocity (D): The speed at which the wave propagates through space.

Analysis and Detail

• The term "depth of the crest" generally refers to how high the wave moves above its equilibrium position (rest position). This is synonymous with the concept of amplitude in wave mechanics.

Verify and Summarize

• Since the question specifically asks for the “depth of the crest,” the correct option is the one that describes the height relative to the equilibrium position.

Final Answer

C. Amplitude
