Its energy : 1.193 x 10⁻¹⁹ J
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]
