Table 1 shows the range of wavelengths for three different bands of infrared radiation.
| Band of Infrared | Range 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.
