The frequency of radiation : 1.2 x 10¹⁵ Hz
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 m/s
λ = wavelength
Wavelength-λ is 2.51 x 10⁻⁷m
The frequency :
[tex]\tt f=\dfrac{3.10^8}{2.51\times 10^{-7}}=1.2\times 10^{15}[/tex]
