Aphoton has an energy of 1.10 x 10-13 j. what is the
photon's wavelength? what type of electromagnetic
radiation is it?

Wavelength-1.805 × 10^-12 m

Type of electromagnetic radiation-Gamma rays

We are given the following;

Energy of a photon is 1.10 × 10^-13 Joules

We are required to calculate the wavelength's  of photon

We need to know that the energy of a photon is calculated by the formula;

E = hf, but f = c/λ

Therefore;

E = hc/λ , where h is the plank's constant,6.623 × 10^-34 J-s, c is the speed of light, 2.998×10^8 m/s and λ is the wavelength.

Rearranging the formula;

λ=hc/E

Thus,

λ = (6.623 × 10^-34 J-s × 2.998×10^8 m/s) ÷ 1.10 × 10^-13 J

  = 1.805 × 10^-12 m
