Answer:
b
Explanation:
22) Calculate the energy of a photon of radiation with a frequency of 9.50 x 1013 Hz.
The energy of the photon with a frequency of 9.50×10¹³ Hz is 6.29×10¯²⁰ J
From the question given above, the following data were obtained:
Frequency (f) = 9.50×10¹³ Hz
Planck's constant (h) = 6.626×10¯³⁴ Js
Energy (E) =?The energy of the photon can be obtained as follow:
E = hf
E = 6.626×10¯³⁴ × 9.50×10¹³
E = 6.29×10¯²⁰ JTherefore, the energy of the photon is 6.29×10¯²⁰ J
