Figure 3 shows a graph of the intensity of electromagnetic radiation emitted by a ceramic heating element at different wavelengths.

Figure 3: A graph showing the intensity of emitted electromagnetic radiation on the y-axis (arbitrary units) against wavelength on the x-axis in micrometres (µm) ranging from 0 to 6. The curve starts at zero, rises steeply as wavelength increases, reaches a maximum peak intensity at a wavelength of 2.0 µm, and then decreases gradually towards zero as the wavelength increases up to 6.0 µm.

Describe how the intensity of the radiation varies with wavelength in Figure 3.
