Solution
Dear student
The sounds having frequency more than 20,000 hertz (Hz) are called ultrasonic or ultrasound and the sounds having frequency less than 20 Hz are called infrasonic or infrasound. Both of these sounds cannot be heard by human beings. The audible range for of hearing by human beings is 20 Hz to 20000 Hz. The speed of sound is same for all frequencies in a particular medium. So, speed of ultrasonic sound and infrasonic sound are same in a particular medium.
Infrasonic, with low frequency : The very very low bass in some rock shows, that feels like something hit your chest. You can hear a boom at the same time, since there is also a normal bass accompanying the infrasonic wave. It comes from a huge speaker. Ultrasonic: Dog whistles, that humans can not hear but dogs respond to since they can hear the higher frequencies.
With regards
