Things around you are emitting infrared radiation that includes the wavelength 1.44 10-5 m. What is the energy of the photons?

Answer 1

Things could not get easier than this. I'm sure you are familiar with this equation:

E = hc/λ

Therefore, plug in the numbers and solve for energy.

E = (6.63 x 10^-34 J*s)(3.0 x 10^8 m/s) / (1.44 x 10^-5 m)
E = 1.38 x 10^-20 J
