GCSE Edexcel Physics Combined Science Electromagnetic spectrum: This question is about waves in

Question

This question is about waves in the electromagnetic (e-m) spectrum.

Figure 1 shows some types of radiation that form part of the e-m spectrum and some uses of e-m radiation.

Draw one straight line from each type of e-m radiation to its use.
One line has been drawn for you.

| type of radiation | use of radiation |
| ----------------- | ---------------- |
| infrared          | satellite transmission |
|                   | disinfecting water |
| visible light     | colour photography |
