The electric field of an electromagnetic wave travelling through vaccum is given by the equation ` E = E_(0) "sin"(kx - omegat)` The quantity that is independent of wavelength is

A

`(k)/(omega)`

B

`k omega`

C

`omega`

D

`k`

Text Solution

Verified by Experts

The correct Answer is:
A
`(K)/(omega) = (lamda )/( 2pi v ) = 1/c`
Where c is the speed of electromagnetic wave in vecuum. It is constnat whose valur is `3 xx 10 ^(8) m s ^(-1).`
