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.
Practise AQA GCSE Physics Black body radiation (physics only) with exam-style questions for Foundation and Higher tier. 9 questions covering Emission and absorption of infrared radiation and Perfect black bodies and radiation, matched to the AQA GCSE Physics (8463) specification and written in Paper 1 and Paper 2 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
