Question

Short note on frequency amplitude and wavelength

Answer 1

Answer:

Explanation:

AMPLITUDE :

A wave is composed of a crest and trough. Amplitudquenquency e is the maximum height of crest (or trough in opposite direction ) from mean position.

Intensity of a wave is directly proportional to amplitude square

Intensity of the wave is energy (energy density when dealing with electrodynamics) per unit area .

FREQUENCY:

It is the number of waves ( one crest and one trough composite a wave) passing through a point in one second.

f =1/Time period

frequency is directly proportional to energy of wave.

WAVE LENGTH :

Distance between two adjacent crests or troughs.

$Velocity of wave =  wavelength * frequency$
