NEET Chemistry (general) MCQ Question
Type: MCQ-numerical-Medium-Class 11
A photon detector receives a total energy of 3.15 × 10^(-18) J from radiation of wavelength 600 nm. How many photons does the detector receive?
A
7.95
B
3.15
C
1.89
D
5.25
Correct Answer
Option A
Detailed Explanation
The energy of one photon is calculated using E = hc/λ, where h = 6.626 × 10^(-34) J s and c = 3 × 10^8 m/s. The total number of photons is the total energy divided by the energy of one photon.
