Question

define the term and State there SI unite (A) wave length (B) time period (C) amplitude and establish the relation velocity with wavelength, represent in symbol form

Answer 1

$\\ \mathfrak{ \huge{ \red{ \underline{ \underline{Answer}}}}} \\ \\ \red{ \star} \: \boxed{ \bold \blue{Wavelength \: ( \lambda)}}$

=> Distance between two peak of wave is called as wavelength.

or

=> wavelength is the distance between two successive crests or throughs of a wave.

=> SI unit = m(metre)

$\green{ \star} \: \boxed{ \bold \blue{Time \: Period \: (T)}}$

=> Time requires to complete one oscillation is called as time period.

or

=> Time requires to cover the distance equal to wavelength is called as time period.

=> SI unit = s(second)

$\red{ \star} \: \boxed{ \bold \blue{Amplitude \: (A)}}$

=> maximum displacement from mean position is called as amplitude.

=> SI unit = m(metre)
