Question

The speed of a transverse wave on a string is 450 m/s, and the wavelength is 0.19 m. The amplitude of the wave is 1.6 mm. How much time is required for a particle of the string to move through a total distance of 1.0 km?

Answer 1

Answer: 2.22s

Explanation: wave speed = 450 m/s, A = amplitude = 1.6mm, λ= wavelength = 0.19m

Wave speed = distance traveled / time taken

Distance traveled = 1km = 1000 m

450 = 1000/ t

t = 1000/ 450 = 2.22s
