Question

10 crests and 10 troughs are produced by à source of sound wave in 0.1 sec Thé separation distance between à c'est and troughs is 50cm calculate thé wavelength fréquency and time period of thé wave

Answer 1

If 10 crest and 10 trough is produced by a source of sound waves in 0.1 seconds then the wavelength is 1 metres and the wavelength between 10 crest and 10 trough if 5 metre.

The frequency is 50 Hz.
