Define :
1 . Wavelength
2 . Frequency
3 . Amplitude
4 . Ultrasounds
5 . Infrasounds
Dear Student,
1) Wave length-The distance moved by a wave in one complete cycle is called its wavelength. In simple words, it is the distance between two consecutive crests or two consecutive troughs propagating in the same phase.
2) Frequency -Frequency can be defined as number of cycles per unit time. The unit of frequency is Hertz (Hz). 1Hz means that an event repeats once per second.
3) Amplitude -The maximum displacement of the particle of medium from its mean position is called Amplitude.

4) Infrasound refers to the sound with frequency lower than 20 Hz which cant be heard by humans.
5) Ultrasound refers to the sound with frequency higher than the upper limit (20 kHz) of frequencies audible to normal human ears.
