Question

A source of sound has a frequency of 300 Hz and a wave length of 60 cm. then its velocity is​

Answer 1

Explanation:

refer the picture

velocity=frequency×Wavelength

Answer 2

Answer: 180m/s

Explanation: wave velocity=wavelength x frequency-1

wave length=0.6m

frequency=300 Hz

= substitute in 1

wave velocity=0.6 x 300

                      = 180m/s
