The energy of a photon is 4.23 x 10-17 J. What is the wavelength of the radiation?

Sagot :

The wavelength of the radiation is 4.7 x 10⁻⁹ m

What is the Einstein's Formula for Energy?

The energy

E is given, from Einstein's formula, as:

E=h⋅ν

Where:

h=6.63×10⁻³⁴Js is Planck's constant;

ν is the frequency.

You can relate frequency and wavelength

λ through the speed of light c as:

c=λ⋅ν

So finally you get:

E=hc/λ

It is given in the question

The energy of a photon is 4.23 x 10⁻¹⁷ J.

Wavelength = ?

λ = hc/E

λ = 6.63×10⁻³⁴x 3 x 10⁸ /  4.23 x 10⁻¹⁷

λ = 4.7 x 10⁻⁹ m

Therefore the wavelength of the radiation is 4.7 x 10⁻⁹ m .
