A tuning fork of unknown frequency gives 4 beats/sec with a tuning fork of frequency 310Hz.It gives the same no. of beats/sec on filing.find the unknown frequency.
The correct answer is (b) 480 Hz
EXPLANATION:
The simple harmonic disturbance produced by the tuning fork is transmitted to the wire through the bridges in the sonometer. Hence the wire will...
The correct answer is (d) 16 kg.
EXPLANATION:
Since the wire is made to vibrate with the same tuning fork the frequency of vibration remains the same.
Equating the frequencies in both the...
(c) Wavelength .
EXPLANATION:
When the sound wave is being sent by a tuning fork, its displacement amplitude, frequency and the time period will remain the same even if the temperature changes....
The correct answer is (a) 506 Hz
EXPLANATION:
The frequency of beats ν = |ν₁-ν₂| = 6 Hz where ν₁ = 512 Hz, ν₂ = frequency of sonometer. Thus ν₂ is either...
(a) larger wavelength
(c) larger velocity
EXPLANATION:
The velocity of sound V is directly proportional to the square root of the temperature. So if the temperature increases the velocity of the sound also...
