A wave travels along a stretched horizontal rope. The vertical distance from crest to trough for this wave is 13 cm and horizontal distance from crest to trough is 28 cm.

(A) What is the wavelength of this wave?

(B) What is the amplitude of this wave?

(A) The wavelength of this wave is .

(B) The amplitude of this wave is .

Explanation:

Refer to the diagram attached. A point on this wave is at a crest or a trough if its distance from the equilibrium position is at a maximum.

The amplitude of a wave is the maximum displacement of each point from the equilibrium position. That's the same as the vertical distance between the crest (or the trough) and the equilibrium position.

Therefore, the amplitude of the wave is exactly the vertical distance between a crest and a trough. Hence, for the wave in this question,

.

The wavelength of a transverse wave is the same as the minimum (horizontal) distance between two crests or two troughs. That's twice the horizontal distance between a crest and a trough in the same period.
