Questions  

Photon and electron are given same energy (10-20J).Wavelength associated with photon and electron are (λph and λel) then correct statement will be

a
λph>λel
b
λph<λel
c
λph=λel
d
λelλph=C

detailed solution

Correct option is A

Wavelength of photon will be greater than that of electron because mass of photon is less than that of electron ⇒λph>λe
