Answer:
The distance between adjacent antinodes of the standing wave is 1.25 m.
Explanation:
Given that,
Frequency f= 120 MHz
We need to calculate the distance between adjacent antinodes of the standing wave
Using formula of distance
.....(I)
We know that,
Put the value of in to the equation (I)
Where, c = speed of light
f = frequency
Put the all value into the formula
Hence, The distance between adjacent antinodes of the standing wave is 1.25 m.
Distance=SPEED*Time(Scalar)
Displacement=VELOCITY*Time(Vector)
Disp= (3m/s)(1.8s) =5.4m
I'm going to quote something that might help you...
"The Doppler effect is the apparent change in the frequency of a wave motion when there is relative motion between the source of the waves and the observer. Well known examples include the change in pitch of an ambulance or police siren, as it approaches and then recedes from you, or the same effect from a passing train."
This is not mine I am simply quoting something that might help you.
