Calculate the wavelength of a sound wave whose frequency is `220 Hz` and speed is `440 m//s` in a given medium.

Calculate the wavelength of a soundwave where frequency is 200Hz and speed is 400ms^(-1) in a given medium.

Calculate the wavelength of a sound wave having a frequency 300 Hz and speed 330 m//s .

The speed of sound wave in a given medium is

Velocity of sound is given by the expression, v= f xx lambda Where, v= velocity of the wave, f = frequency, lambda = wavelength Using the above information answer the following questions Calculate the wavelength of radio waves of frequency 10^(9) Hz. The speed of radio waves is 3 xx 10^(8)m//s

(a) Name four ways in which sound can be produced. (b) Calculate the speed of a sound wave whose frequency is 2kHz and wavelength 65 cm.
