A source of sound gives 5 beats per second, when sounded with another source of frequency 100 
. The second harmonic of the source, together with a source of frequency 205 
gives 5 beats per second. What is the frequency of the source?
Text Solution
Verified by ExpertsA
Frequency of first source with 5 beats/sec 
and frequency of second source with 5 beats/sec 
The frequency of the first source 
or 95 Hz.
Therefore, frequency of second harmonic source 
Hz or 190 Hz.
As the second harmonic gives 5 beats/second with the sound of frequency 205 Hz, therefore frequency of second harmonic source should be 210 Hz. The frequency of source 
Hz.
