What is the energy of a photon of ultraviolet radiation with a frequency of 4.4 × 1015 hz? planck’s constant is 6.63 × 10–34 j • s. 2.9 × 10–18 j 2.9 × 10–34 j 2.9 × 10–48 j

Answer 1

The energy of a photon of ultraviolet radiation is E = 2.91 * 10^-18 J

What is a photon?

A photon is a particle of light defined as a discrete bundle (or quantum) of electromagnetic energy.

The energy of a photon is obtained by multiplying Planck's constant by the frequency of electromagnetic radiation:

E = h * f

where,

h is Planck's constant

h= 6.63×10⁻³⁴ Js

f= 4.4×10^15 Hz

Substituting the values in the equation for Energy:

E = (6.63×10⁻³⁴) * ( 4.4×10^15)

E = 2.91 * 10^-18 J

Hence,

The energy of a photon of ultraviolet radiation is E = 2.91 * 10^-18 J
