The energy of a single photon of this frequency is 1.638 × 10⁻¹⁸ J
Using Planck's equation, the energy of the photon E = hf where h = Planck's constant = 6.63 × 10⁻³⁴ Js and f = frequency of ultraviolet light = 2.47 × 10⁻¹⁵ Hz.
Substituting the values of the variables into the equation, we have
E = hf
E = 6.63 × 10⁻³⁴ Js × 2.47 × 10¹⁵ Hz.
E = 16.3761 × 10⁻¹⁹ J
E = 1.63761 × 10⁻¹⁸ J
E ≅ 1.638 × 10⁻¹⁸ J
So, the energy of a single photon of this frequency is 1.638 × 10⁻¹⁸ J
