Question

define frequency, wavelength, time period, amplitude​

Answer 1

Frequency :- the number of vibration made by a particle of a medium in one second is called frequency.

Wavelength :- the distance travelled by the wave in one time period of vibration of particles of medium is called wavelength.

Time period :- the time taken by a particle medium to complete its one vibration is called the time period of the wave.

Amplitude :- the maximum displacement of the particle of medium on either side of the mean position is called amplitude of the wave

Answer 2

Answer:

Frequency

the rate at which something occurs over a particular period of time or in a given sample.

"an increase in the frequency of accidents due to increased overtime

Wavelength=the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.

the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave."a range of wavelengths"

Time period=time period (denoted by 'T' ) is thetime taken for one complete cycle of vibration to pass a given point. As the frequency of a wave increases, thetime period of the wave decreases. ... The period of a pendulum is the time it takes from one side to the other and back.

Explanation:

Amplitude =maximum extent of a vibration or oscillation, measured from the position of equilibrium.

maximum extent of a vibration or oscillation, measured from the position of equilibrium."the amplitude of alpha rhythms"
