Longer wavelength means higher frequency and lower energy. Longer wavelength means lower frequency and higher energy. Longer wavelength means higher frequency and higher energy.
Longer wavelength means lower frequency and lower energy.
Because different photons travel at different speeds, there is no simple relationship. Assume the electrons are absorbing energy and thus producing an absorption spectrum. Suppose the surface temperature of the Sun were about 36,000 K, rather than 6,000 K. List two ways in which the thermal radiation spectrum of the Sun would be different. A planet is five astronomical units from the Sun. Part of the cloud of gas lies between us and another hot thermal source.
