A thermometer left lying in sunlight shows an increasing temperature. Today, we would say that light transfers energy from the Sun to the Earth, and when it is absorbed, energy is stored thermally in the absorbing … Zobacz więcej Before experimenting with his filters, Herschel needed to know about the heating effect of different colours of light.
