The maximum displacement of the body in vibration.
The time taken by a body to complete one vibration.
Frequency is the number of oscillations completed in a unit time
(f = 1/T).
The natural frequency of a body executing forced vibrations is equal to the input frequency. The body vibrates with maximum amplitude. The frequency is called resonant frequency
A mechanical wave is just a disturbance that propagates through a medium
An electromagnetic wave is simply light of a visible or invisible wavelength. Oscillating intertwined electric and magnetic fields comprise light. Light can travel without medium
In a transverse wave the particles in the medium move perpendicular to the direction of the wave. Eg. Light waves, waves on strings.
The particles in the medium move parallel to the direction of the wave. Eg. Sound waves
The superposition of two waves of the same frequency and wavelength traveling with a phase difference which remains constant with time. This phenomenon is called interference. The pattern so formed is called interference pattern.
Superposition of two waves of same amplitude and wavelength moving in opposite direction with no energy propagation.
The points of no displacement when standing waves are formed.
The points along the medium which vibrate back and forth with maximum displacement.
