Concept explainers

Stretched string

A stretched string is a wire which is made up of any metal that must have a larger length compared to its thickness. The ends of the wire are fixed, and when they oscillate or are plucked, it produces two reflected transverse waves of the same frequency and same amplitude. The waves or pulses are traveling in alternate directions and superimpose with one another. This waveform is named standing or stationary waves.

Question

Water waves from a source far to the left (not shown) travel in the rightward direction and disturb the height of the
water by a maximum displacement A from the equilibrium level (dashed line). Mo the Marmot sits on a boat, which goes
up and down as the traveling harmonic water wave passes by. Figure 1 shows a snapshot of this at some time. Figure 2
shows measurements of the vertical displacement from equilibrium, y, of Mo's boat as a function of time, which he
recorded with his ioLab device.
