Here is a graph of intensity v/s the wavelength of the radiation plotted at different temperatures. If the wavelength is more, the frequency of the radiation is very less. The intensity of the wave will be more if the wavelength is small, and as the wavelength increases, the intensity will get reduced.

This is because the energy of the incident light is reduced by entering into the denser medium and the energy is absorbed by the system converting it into thermal energy thus raising the temperature of the system. The wavelength of the waves emitted by the system is always less than the wavelength of the incident waves absorbs by the system. If we consider the wavelength of the radiated waves, then now we can write the relation between the intensity and the wavelength by the equation, The radiation with high intensity basically comprises of waves having high frequency and energy.Īs the frequency of the refracted waves decreases on giving off the energy to the system, the emitted waves are of long wavelength and thus less intensity. Does the Intensity of Radiation depend upon the Wavelength? Read more on How is heat transferred by radiation: Exhaustive explanation. The power of radiation is directly proportional to the fourth power of the temperature by the formula,Īs the temperature of the system increases, the intensity of radiation of the system also increases. The intensity of light will be responsible for the rise in temperature of the system as the agility of the molecules will increase and thus escalating the radiation intensity. If the temperature of the system is high then the emission of radiation is more from the system. The intensity of radiation depends upon the intensity of incident waves and the angle at which these waves are incident. Does the intensity of Radiation depend upon the Temperature? Hence, the intensity of the radiation will be more in the case of bright coloured objects. The dark coloured objects emit very few radiations as compared to bright coloured objects. The intensity of the radiation depends upon the emissivity of the object. The emissivity of the object depends upon the intensity of the incident waves on the object, dimensions, composition, and colour. Does the intensity of Radiation depend upon Emissivity?

The radiated waves at an angle ‘θ’ are emitted in this area ‘A’. The area covered by the cone making an angle ‘θ’ is.
