WebThe wavelength of peak emission relies on the temperature of the object emitting radiation. A higher temperature will lead the wavelength of peak emission to be at a shorter wavelength. Step 3: The temperature of an object is precisely related to the average speed of the molecules which forms an object. WebWien’s Displacement Law, which states that the frequency of the peak of the emission (f max) increases linearly with absolute temperature (T). Conversely, as the temperature of the body increases, the wavelength at the emission peak decreases. 3. Stefan–Boltzmann Law, which relates the total energy emitted (E) to the absolute temperature (T). WebEmission Peak.
