Question

Given that sound travels in air at 340m/sec, find the wavelength of the waves in air produced by 20 kHz sound source. If the some source is put in a water tank, what would be the wavelength of the sound waves in water? Speed od sound in water is 1480m/s

Answer 1

velocity = frequency × wavelength  

340= 20 × x

x = 340/20

x= 17 cm

frequency in water  

1480/20=x

x = 74 cm

Answer 2

$\huge{hey!!}$

_______

velocity = frequency × wavelength

340 = 20 × X

X = 340/20

X = 17 cm

frequency in water = 1480 /20

= 74 cm
