Question

A wave travels from the center of a pond to the edge. The distance from the center to the edge is 14.6m. The wave takes 32 seconds to reach the edge. As the wave proceeds towards the edge, the particles of water in the pond rise up to 0.2m above the calm surface. They complete 1 oscillation in 1.2s.
a. What is the wave transfering?
b. What is the time-period of the wave?
c. Calculate the frequency of the wave.
d. Calculate the velocity of the wave.
e. Calculate the wavelength of the wave.
f. What is the amplitude of the wave?
g. What type of material wave is it?

Answer 1

Explanation:

1)wave transfer energy through particles present in the substance

2)time period=1/frequncy=1/0.833hz=1.2s

3)frequency=no of oscillation/time taken=1/1.2

=0.833Hz

4)distance =14.6m

time=32s

wave velocity=14.6/32=0.45625m/s

wave length=54.7cm

calculation in picture

amplitude = maximum dicplacement of the particle=0.2m
