The energy of a photon when the frequency is 10 GHz is 4.14 x 10⁻⁵ eV.
The energy of a photon when the frequency is 30 MHz is 1.24 x 10⁻⁷ eV.
<h3>
Energy of a photon</h3>
The energy of a photon is calculated from the product of frequency and Planck's constant.
E = hf
where;
- h is Planck's constant
- f is frequency of the photon
<h3>when the frequency = 5 x 10¹⁴ Hz</h3>
E = 6.626 x 10⁻³⁴ x 5 x 10¹⁴
E = 3.313 x 10⁻¹⁹ J
E = (3.313 x 10⁻¹⁹ J) / (1.6 x 10⁻¹⁹)
E = 2.07 eV
<h3>when the frequency = 10 GHz = 10 x 10¹⁰ Hz</h3>
E = 6.626 x 10⁻³⁴ x 10 x 10¹⁰
E = 6.626 x 10⁻²⁴ J
E = (6.626 x 10⁻²⁴ J) / (1.6 x 10⁻¹⁹)
E = 4.14 x 10⁻⁵ eV
<h3>when the frequency = 30 MHz = 30 x 10⁶ Hz</h3>
E = 6.626 x 10⁻³⁴ x 30 x 10⁶
E = 1.988 x 10⁻²⁶ J
E = ( 1.988 x 10⁻²⁶ J) / (1.6 x 10⁻¹⁹)
E = 1.24 x 10⁻⁷ eV
