Your explanation should refer to an equation in the Equation Booklet.

Ultraviolet (UV) waves from the Sun travel towards the Earth.

Ultraviolet waves can be grouped by wavelength.

The three groups of wavelengths are UVA, UVB and UVC.

Figure 4 shows, for each group,

UV radiation of wavelength 365 nm is used to detect forged banknotes.

In a genuine banknote there are marks that cannot be seen using visible light. These marks can be seen using UV radiation.
