Three different vibrating bodies produce three types of sounds X, Y and Z. Sounds X and Y cannot be heared by a man having normal range of hearing but sound Z can be heard easily. The sound X is used in for monitoring nuclear reactor.Y is sound similar to that which is produced during an earthquake before the main shock wave is generated. What type of sounds are (i) X (ii) Y, and (iii) Z?

The correct option is D X-ultrasound
Y-infrasound
Z-audible sound
Infrasound is the sound where the rate of vibration is too low for us to hear
Ultrasound is the sound where the rate of vibration is too high for us to hear
Ultrasound is used to see what is happening in a nuclear reactor.Ultrasounds and infra sounds are not audible to man.Ultrasound have frequency more than 20kHz. Infrasound have frequency below 20Hz.An earthquake produces infrasound before the mainshock wave begins.
Since Z can be heard by a person so Z is in audible range and it is audible sound.
