JEE Mains · Physics · STD 12 - 11. Dual nature of radiation and matter
A particle of mass \(9.1 \times 10^{-31}\, {kg}\) travels in a medium with a speed of \(10^{6}\, {m} / {s}\) and a photon of a radiation of linear momentum \(10^{-27} \,{kg}\, {m} / {s}\) travels in vacuum. The wavelength of photon is \(....\) times the wavelength of the particle.
- A \(730\)
- B \(880\)
- C \(840\)
- D \(910\)
Answer & Solution
Correct Answer
(D) \(910\)
Step-by-step Solution
Detailed explanation
\(\because\) We know that, de-Broglie wavelength can be given as \(\lambda=\frac{h}{m v}\) \(\therefore\) For particle, \(\lambda_{ pa }=\frac{h}{m v}=\frac{6.6 \times 10^{-34}}{9.1 \times 10^{-31} \times 10^{6}}\) and for photon,…
