A photon has a momentum of \(3.3 \times 10^{-29} kg m / s\). The frequency of the waves associated with the photon will be (Given: \(h=6.6 \times 10^{-84} Js\) )
- A \(1.3 \times 10^3 Hz\)
- B \(2.6 \times 10^3 Hz\)
- C \(7.5 \times 10^{12} Hz\)
- D \(1.5 \times 10^{13} Hz\)
Answer & Solution
Correct Answer
(D) \(1.5 \times 10^{13} Hz\)
Step-by-step Solution
Detailed explanation
\(f = \frac{pc}{h}\) \(f = \frac{(3.3 \times 10^{-29} kg m / s) \times (3 \times 10^8 m/s)}{(6.6 \times 10^{-34} Js)}\) \(f = 1.5 \times 10^{13} Hz\)
