Its energy : 1.193 x 10⁻¹⁹ J

Further explanation

Radiation energy is absorbed by photons

The energy in one photon can be formulated as

[tex]\large{\boxed{\bold{E\:=\:h\:.\:f}}}[/tex]

Where

h = Planck's constant (6,626.10⁻³⁴ Js)

f = Frequency of electromagnetic waves

f = c / λ

c = speed of light

= 3.10⁸

λ = wavelength

[tex]\tt E=6.626\times 10^{-34}\times 1.8\times 10^{14}\\\\E=1.193\times 10^{-19}~J[/tex]
