Ultrasonic waves of frequency 4.5 MHz are used to detect tumour in soft tissues. The speed of sound in tissue is `1.5 km s^-1` and that in air is `340 m s^-1`. Find the wavelength of this ultrasonic wave in air and in tissue.

Diagnostic ultrasound of frequency 3.80 MHz is used to examine tumors in soft tissue. (a) What is the wavelength in air of such a sound wave? (b) If the speed of sound in tissue is 1500 m/s, what is the wavelength of this wave in tissue?

The frequency of the sound wave having velocity 340 m s^(-1) is 5 kHz. Find out the wavelength of this sound wave in air.

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

Two tuning forks having frequencies 320Hz and 340Hz are sounded together to produce sound waves. The velocity of sound in air is 326.4 m s^-1 . Find the difference in wavelength of these waves.

The speed of sound waves in air is 340 m/s and 5600 m/s through steel. The wavelength of a 1000 Hz acoustic wave travelling from air to steel will

A bat emits ultrasonic waves of frequency 39 kHz and receives and echo 0.2 s later. If the speed of sound in air is 300 m/s and the speed of electro magnetic waves 3 xx 10^(8) m//s then the distance of the bat from the object producing the echo is
