The frequency of electromagnetic wave which is best suit to observe a particle of radius `3xx10^(-4)` is of order of:

Options

A. `10^(15)`
B. `10^(14)`
C. `10^(13)`
D. `10^(12)`

Answer

B

Explanation

Radius of particle is `lambda`
`:.v=(c)/(lambda)=(3xx10^(8))/(3xx10^(-6))=10^(14)`
For observation of particle the wave frequency should be more than `10^(4) Hz`, or wave length should be smaller.
