What is the frequency of a photon of light that has an energy of 2.95 × 10−17 J

Sagot :

The frequency of the photon of light is 4.4 * 10¹⁶ Hz

Energy and frequency of light

  • The energy and frequency of light are related by the formula given below:
  • E = hf

Where h is Planck's constant = 6.626 * 10⁻³⁴

f is frequency

E = energy

making f subject of the formula

f = E/h

f = 2.95 × 10⁻¹⁷/6.626 * 10⁻³⁴

f = 4.4 * 10¹⁶ Hz

Therefore, the frequency of the photon of light is 4.4 * 10¹⁶ Hz
