Question

source
of sound has frequency
2000 Hz. If the speed of sound in air is 340
hind the distance covered by sound when the
source completes 400 vibrations.​

Answer 1

Answer:

velocity=frequency wavelength 330=2000xwavelength

33-200=wavelength

so

after 400 vibrations,

the equation will be

length covered by wave

={no. of vibrations wavelength}3D2

=(400x33-200)-2

=66÷2

=33
