Question

A child is sending pulses down a stretched rope at a rate of 2 pulses per second. The distance between the pulses is 5 meters. What is the speed of the wave?

a. 5 m/s
c. 2 Hz
b. 10 m/s
d. 2.5 m/s User: Longitudinal seismic waves are known as
a. primary waves.
b. secondary waves.
c. surface waves.
d. transverse waves.

Answer 1

Wave speed = (wavelength) x (frequency)

= (5 meters) x (2 per second)

= 10 meters per second .
