JEE Mains · Physics · STD 12 - 11. Dual nature of radiation and matter

द्रव्यमान \(m\) के इलेक्ट्रोन तथा किसी फोटॉन की ऊर्जाएं \(E\) एकसमान है। इनसे संबद्भ दे-ब्राग्ली तरंग दैर्ध्यो का अनुपात है :

  1. A \({\left( {\frac{E}{{2m}}} \right)^{\frac{1}{2}}}\)
  2. B \(\;C{\left( {2mE} \right)^{\frac{1}{2}}}\)
  3. C \(\;\frac{1}{C}{\left( {\frac{{2m}}{E}} \right)^{\frac{1}{2}}}\)
  4. D \(\;\frac{1}{C}{\left( {\frac{E}{{2m}}} \right)^{\frac{1}{2}}}\)
Verified Solution

Answer & Solution

Correct Answer

(D) \(\;\frac{1}{C}{\left( {\frac{E}{{2m}}} \right)^{\frac{1}{2}}}\)

Step-by-step Solution

Detailed explanation

For electron of energy \(E\) de-Broglie wavelength, \(\lambda_{e}=\frac{h}{p}=\frac{h}{\sqrt{2 m E}}\) For photon of energy, \(E=h v=\frac{h c}{\lambda_{p}}\) \({\Rightarrow \lambda_{p}=\frac{h c}{E}}\)…
