Find the period and speed of the wave:

Question

A periodic wave traveling in a uniform medium has a wavelength of 0.080 meter, an amplitude of 0.040 meter and a frequency of 5.0 Hertz.

(a) Determine the period of the wave

(b) Calculate the speed of the wave

Answer 1

(a)

 

T = 1/f = 1/(5.0 Hz) = 0.20 s

 

(b)

 

v = λf = (0.080 m)(5.0 Hz) = 0.40 m/s
