Question

Photon and electron are given same energy (10^–20 J). Wavelength associated with photon and electron are l_Ph and l_el , then correct statement will be –

• A. l_Ph>l_el
• B. l_Ph<l_el
• C. l_Ph= l_el
• D. $\frac{\lambda_{el}}{\lambda_{Ph}}$ = C

Answer 1

Answer: (A)

l_Ph>l_el

Answer 2

E_Ph = E_el = 10^–20 J < 1 Mev

l_e < l_Ph
