Photon and electron are given same energy `(10^(-20) J)`. Wavelength associated with photon and electron are `lambda_(ph)` and `lambda_(el)` then correct statement will be

Options

A. `lamda_(p) gt lamda_(e)`
B. `lamda_(p) lt lamda_(e)`
C. `lamda_(p)=lamda_(e)`
D. `(lamda_(e))/(lamda_(p))=c`

Answer

A

Explanation

Wavelength of photon will be greater than that of electron because mass of photon is less than that of electron `implies lamda_(p) gt lamda_(e)`.
