1 . Wavelength
2 . Frequency
3 . Amplitude
4 . Ultrasounds
5 . Infrasounds
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.Regards
2)the rate at which something occurs over a particular period of time or in a given sample.
3)the maximum extent of a vibration or oscillation, measured from the position of equilibrium.
4)sound waves with frequencies below the lower limit of human audibility.
5)sound or other vibrations having an ultrasonic frequency, particularly as used in medical imaging.
2. the no. of oscillations per unit time.
3. the maximum displacement on either side of mean value is called amplitude.
4. sounds with frequency less than 20 Hz
5. sounds with frequency more than 20 KHz
