Calculate the energy range of visible photons

WebInfrared photons are invisible to the human eye, but can be felt as "heat rays" emitted from a hot solid surface like a cooling stove element (a red-hot stove or oven element gives off a small amount of visible light, red, but most of the energy emitted is in the infrared range). Hope this helps. WebThe frequency range of visible light is from 3.75 × 10 14 H z to 7.5 × 10 14 H z. Calculate its wavelength range. Calculate its wavelength range.
