2016Final pdf . wPS TH5 6 5. (5 pointe) For the wave shown in the disgram below, identify or calculate the following values: 0.3 (a) The amplitude: (b) The wavelength: (c) The period: (d) The frequency: (e) The wave speed: 6. (5 points) (a) Explain, in your own words, what the Doppler effect is and how it relates to red-shifted and blue-shifted light. b) If an object travels as fast as (or fiaster than) the sound waves it produces, the result is a sonic Is there something similar to a sonic boom for light waves in a vucuum? Why or why not?

Explanation / Answer

Here ,

part a)

Amplitude , A = 0.3/2 m

amplitude = 0.15 m  

part b)

wavelength = 0.40 m

part c)

Now, as v = wavelength/T

T = 0.40/3.2

T = 0.125 s

part d)

frequency = 1/T

frequency = 1/.125

frequency = 8 Hz

part e)

wave speed = 3.2 m/s
