Wave Motion and Sound Summary
WAVE is a form of disturbance, which travels through a material medium due to the repeated periodic motion of the particles of the medium about their position.
Mechanical wave is a periodic disturbance, which requires a material medium for its propagation.
Electromagnetic wave is a disturbance, which does not require any material medium for its propagation and can travel even through vacuum.
Longitudinal wave is a wave motion in which the particles of the medium oscillate about their mean positions in the direction of propagation of the wave.
Transverse wave is a wave motion in which the particles of the medium oscillate about their mean positions at right angles to the direction of propagation of the wave.
Pulse is a sudden and short disturbance.
Wavelength is the distance between the two nearest points on a wave.
Frequency is the number of waves produced per second.
Time period is the time taken by a wave to travel a distance equal to its wavelength.
Wave velocity is the distance traveled by a wave in one second.
