An industrial technician is monitoring the thermal radiation emitted by a silicon carbide heating element inside a high-temperature kiln.
The graph below displays how the spectral intensity of the emitted thermal radiation varies with wavelength for two different operating temperatures, TlowT_{\text{low}}Tlow and ThighT_{\text{high}}Thigh, where ThighT_{\text{high}}Thigh is a higher operating temperature than TlowT_{\text{low}}Tlow.
Describe how the spectral intensity of the emitted radiation changes as the operating temperature of the heating element increases from TlowT_{\text{low}}Tlow to ThighT_{\text{high}}Thigh.
