Question 8
A sound wave has frequency of 2 kHz and wavelength of 35 km. If an observer is 1·4 km away from the source, after what time interval could the observer hear the sound?
Question 9
Ultrasonic Waves of frequency 3 x 105 Hz are passed through a medium where speed of sound is 10 times that in air (Speed of sound in air is 300 m/s). The wavelength of this wave in that medium will be of the order of
