Two opposite charaged particles oscillate about their mean equilibrium position in free space, with a frequency of 10^(9) Hz. The wavelength of the corresponding electromagnetic wave produced is ……..

Answer»

0.3 m
`3XX10^(17)m`
`10^(9)m`
3.3 m

SOLUTION :`c=F lambda RARR lambda = (c )/(f)`
`c=3xx10^(8)m//s`
`f=1xx10^(9)Hz`
`THEREFORE lambda =(3xx10^(8))/(10^(9))=0.3 m`
