- MCQ
Given below are two statements Statement\(-I :\) Two photons having equal linear momenta have equal wavelengths. Statement\(-II :\) If the wavelength of photon is decreased, then the momentum and energy of a photon will also decrease. In the light of the above statements, choose the correct answer from the options given below.
Pick an option to check your answer.
Answer & Solution
Correct Answer
(D) Statement \(I\) is true but Statement \(II\) is false
Step-by-step Solution
Detailed explanation
If linear momentum are equal then wavelength also equal
\(p=\frac{h}{\lambda}, E=\frac{h c}{\lambda}\)
On decreasing wavelength, momentum and energy of photon increases.
