Given below are two statements: Statement I: Two photons having...
Given below are two statements:
Statement Two photons having equal linear momenta have equal wavelengths.
Statement If the wavelength of the 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.
Options
- ABoth Statement and Statement are false
- BBoth Statement and Statement are true
- CStatement is true but Statement is false
- DStatement is false but Statement is true
Correct answer
C. Statement is true but Statement is false
Step-by-step solution
If linear momentum are equal then wavelength also equal.
The momentum and energy of a photon is given by,
; where is speed of light and is Plank's constant.
On decreasing wavelength, momentum and energy of photon increases.
