Question

What will be the relation between wavelength of photon and electron of same energy?

• A. $ {{}_{\text{Ph}}}\text{}\,{{}_{\text{e}}} $
• B. $ {{}_{\text{Ph}}}-\,{{}_{\text{e}}} $
• C. $ {{}_{e}}>\,{{}_{Ph}} $
• D. None of these

Answer 1

Answer: (A)

Wavelength of photon will be greater than that of electron, because mass of photon is less than that of electron. $ {{\lambda }_{ph}}>{{\lambda }_{e}} $
