As your hand moves back and forth to generate longitudinal pulses in a spiral spring, your hand completes 2.91 back-and-forth cycles every 3.67 s. the velocity of the pulse in the spring is 0.925 cm/s. what is the wavelength? answer in units of m.

Wavelength,

Explanation:

Given that,

Number of cycles in a spiral spring is 2.91 in every 3.67 s

The velocity of the pulse in the spring is 0.925 cm/s, v = 0.00925 m/s

To find,

Wavelength

Solution,

Number of cycles per unit time is called frequency of a wave. The frequency of the longitudinal pulse is,

The wavelength of a wave is given by :

So, the wavelength of the longitudinal pulse is 0.011 meters. Hence, this is the required solution.

are there answer choices to this question? this seems like a question where you have options to choose from.
