Quote:They might individually have less energy, but there are an awful lot of them. Total energy received is still significant.
<div>IR photons contain less energy than those in the visible spectrum (E = hf = hc/λ where E is energy, h is Planck's constant, f is the frequency, c is speed of light, λ is wavelength). So I'd be surprised if that were of any worry, but am open to explanations as to why I am mistaken.
