Table 1 shows the range of wavelengths for three different bands of infrared radiation.

Band of InfraredRange of wavelength in nanometres (nm\text{nm}nm)
Infrared-A (IR-A)750–1400
Infrared-B (IR-B)1400–3100
Infrared-C (IR-C)3100–4600

Determine which band of infrared radiation shown in Table 1 has the largest range of wavelengths.

To gain full marks you must calculate the range of wavelengths for each band of infrared radiation.
