Questions Related to interference of sound waves
If the difference between the frequencies of two waves is 10 Hz then time interval between successive maximum intensity is:
The intensity of the sound gets reduced by $10$% on passing through a slab. The reduction in intensity on passing through two consecutive slab, would be
Statement-1:
Two longitudinal waves given by equations; ${ y } _{ 1 }$(x,t) = 2a $\sin { \left( \omega t-kx \right) } $ and ${ y } _{ 2 }\left( x,t \right) $ = a $\sin { \left( 2\omega t-2kx \right) } $ will have equal intensity.
Two coherent sources of different intensities send waves which interfere. If the ratio of maximum and minimum intensity in the interference pattern is $25$ then find ratio of intensity of source :
Statement -1:
Two longitudinal waves given by equation $y _{1}$(x,t) = 2a sin $(\omega - kx)$ and $y _{2}$(x,t) = a sin $(2\omega - 2kx)$ will have equal intensity.
Statement -2:
Intensity of waves of given frequency in the same medium is proportional to the square of amplitude only.
If two waves maintain constant phase difference or same phase at any two points on a wave is known as spatial coherence.
Intensity (I) is related to amplitude (A) as:
The resultant intensity for two identical waves of intensity I with a phase difference of $\pi/3$ is
If the sum of the intensities of two component waves are 5I units and upon superposition with a phase difference of $\pi $ radians, their resultant is 2I, what are the intensities of component waves
Waves from two sources superpose on each other at a particular point amplitude and frequency of both the waves are equal. The ratio of intensities when both waves reach in the same phase and they reach with the phase difference of $90^{\circ}$ will be
