This statement is known as the Rayleigh-Jeans law and is valid in the classical limit. According to the Rayleigh-Jeans law, the average number of photons in equilibrium is proportional to the temperature of the radiation cavity. Mathematically, it can be expressed as:
⟨N⟩ = kT/V
Where ⟨N⟩ is the average number of photons, k is the Boltzmann constant, T is the temperature of the radiation cavity, and V is the volume of the cavity.
It is important to note that the Rayleigh-Jeans law is only valid at low frequencies or long wavelengths, and it fails at high frequencies or short wavelengths. This failure was known as the ultraviolet catastrophe and was resolved by the development of quantum mechanics and the Planck's law of blackbody radiation.
