Let us Practise
1. find the speed of a sound wave that has a wavelength of 0.08 m and a frenquency of 9 Hz.
2. what is the velocity of sound if the temperature of the air is 16°c?
3. find the wavelength of a longitudinal wave travelling with a speed of 0.85 m/s ad a frequency of 6 Hz.
4. a sond wave travelling on a copper wire has a speed od 0.3 m/d the wavelength of this wave is 0.09 m find the frequency of the wave.
5. find the wavelength of a wave that travels a distance of 4.8 meters in 5 second with a frequency of 6 Hz.​
