Answer:
Therefore the the highest frequency is 620Hz and lowest frequency is 580Hz
Explanation:
Given data
Source Frequency fs=600Hz
Length r=1.0m
RPM=100 rpm
The speed of the generator is calculated as:
Substitute the given values
For approaching generator the frequency is calculated as:
On the other hand,for the receding generator,Doppler's effect is expressed as:
Therefore the the highest frequency is 620Hz and lowest frequency is 580Hz
