Two sources of sound 
and 
produces the wave of 350 Hz, in the same phase. The particle 
is vibrating under the influence of these two waves. If the amplitudes at the point 
produces by the two waves is 0.3 mm and 0.4 mm, then the resultant amplitude of the point 
will be (when 
and the velocity of sound is 
)
Text Solution
Verified by ExpertsThe correct answer is:
D
Wavelength, 
Also, path difference ( 
) between the waves at the point of observation is 
.
Hence, Path difference,
