Question

Calculate the energy of a photon whose frequency is 1300kHz

Answer 1

Answer:-

not the right answer. but the steps are useful to you

frequency = 20 MHz = 20×10⁶ Hz

Energy = hf = 6.626 × 10⁻³⁴ × 20 × 10⁶ = 1.3252×10⁻²⁶ joules

Energy of photon is 1.3252×10⁻²⁶ joules

Answer 2

Answer:

8.58 x10^(-28) jule

Explanation:

E=hf h=planks constant, f=frequency

E=6.6*10^(-34)*1300*1000HZ

E=8.58 x10^(-28) jule
