A source of unknown frequency gives 4 beats/s, when sounded with a sou...
Solution:
Given:
Frequency of first source = x Hz (unknown frequency)
Frequency of second source = 2x Hz (second harmonic of unknown frequency)
Frequency of third source = 250 Hz
Frequency of fourth source = 513 Hz
Beats produced in the first case = 4 beats/s
Beats produced in the second case = 5 beats/s
To find: The value of x
1. Calculation of x using the first case:
When the two sources are sounded together, beats are produced at a frequency equal to the difference in their frequencies.
Let the frequency of the first source be x Hz and the frequency of the third source be 250 Hz.
The beats produced are 4 beats/s.
So, the difference between the frequencies of the two sources is 4 Hz.
Therefore, x - 250 = 4
So, x = 254 Hz.
2. Calculation of x using the second case:
When the second and fourth sources are sounded together, beats are produced at a frequency equal to the difference in their frequencies.
Let the frequency of the second source be 2x Hz and the frequency of the fourth source be 513 Hz.
The beats produced are 5 beats/s.
So, the difference between the frequencies of the two sources is 5 Hz.
Therefore, 2x - 513 = 5
So, 2x = 518
So, x = 259 Hz.
But, the value of x obtained from the first case is x = 254 Hz.
Therefore, the correct option is (a) 254 Hz.
Given:
Frequency of first source = x Hz (unknown frequency)
Frequency of second source = 2x Hz (second harmonic of unknown frequency)
Frequency of third source = 250 Hz
Frequency of fourth source = 513 Hz
Beats produced in the first case = 4 beats/s
Beats produced in the second case = 5 beats/s
To find: The value of x
1. Calculation of x using the first case:
When the two sources are sounded together, beats are produced at a frequency equal to the difference in their frequencies.
Let the frequency of the first source be x Hz and the frequency of the third source be 250 Hz.
The beats produced are 4 beats/s.
So, the difference between the frequencies of the two sources is 4 Hz.
Therefore, x - 250 = 4
So, x = 254 Hz.
2. Calculation of x using the second case:
When the second and fourth sources are sounded together, beats are produced at a frequency equal to the difference in their frequencies.
Let the frequency of the second source be 2x Hz and the frequency of the fourth source be 513 Hz.
The beats produced are 5 beats/s.
So, the difference between the frequencies of the two sources is 5 Hz.
Therefore, 2x - 513 = 5
So, 2x = 518
So, x = 259 Hz.
But, the value of x obtained from the first case is x = 254 Hz.
Therefore, the correct option is (a) 254 Hz.
