A thin metal plate is placed against the teeth of cog wheel. Cog wheel is rotated at a speed of 120 rotations per minute and has 160 teeth. Calculate:
- frequency of node produced.
- speed of sound, if wavelength is 1.05 m.
- what will be the effect when the speed of cog wheel is doubled?
Two tuning forks A and B of frequencies 256 Hz and 192 Hz respectively are vibrated in air. If the wavelength of A is 1.25 m, calculate the wavelength produced by B.
