If the temperature is = C = K, then the wavelength at which the radiation curve peaks is: λ peak = x10^ m = nm = microns. This wavelength corresponds to quantum energy. hν = x 10^ eV.

In physics, the intensity or flux of radiant energy is the power transferred per unit area, where the area is measured on the plane perpendicular to the direction of propagation of the energy. In the SI system, it has units watts per square metre (W/m ), or kg⋅s in base units. Intensity is used most frequently with waves such as acoustic waves (sound) or electromagnetic waves such as light or radio waves, in which case the average power transfer over one period of the wave is used. Intensi… WebThe amount of energy that is transported by a sound wave past a given area of the medium per unit of time is known as the intensity of the sound wave. Intensity is the …
