1 Answer

Frequency: Frequency is the number of cycles per second.

Bandwidth: A range of frequencies within a given band, in particular that used for transmitting a signal.

Wavelength: Wavelength can be defined as the distance between two successive

crests or troughs of a wave. It is measured in the direction of the wave.

Time period: A Time period (denoted by 'T' ) is the time needed for one complete cycle of vibration to pass a given point.

 OR

Time period=1/frequency
