### Answer by Gurmeet Kaur

## Answer - option (d)

The Electro-Magnetic or EM radiation is classified into types according to the frequency of the wave: these types include, in order of increasing frequency, radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, **X-rays** and gamma rays.

| **Category** \ | **Range of Wavelengths (nm)** \ | **Range of Frequencies (Hz)** \ |
| --- | --- | --- |
| Gamma rays \ | <1<1 \ | >3×1017>3×1017 \ |
| X-rays \ | 1–101–10 \ | 3×1016–3×10173×1016–3×1017 \ |
| Ultraviolet light \ | 10–40010–400 \ | 7,5×1014–3×10167,5×1014–3×1016 \ |
| Visible light \ | 400–700400–700 \ | 4,3×1014–7,5×10144,3×1014–7,5×1014 \ |
| Infrared \ | 700–105700–105 \ | 3×1012–4,3×10143×1012–4,3×1014 \ |
| Microwave \ | 105–108105–108 \ | 3×109–3×10123×109–3×1012 \ |
| Radio waves | >108>108 | <3×109 |

These are some examples of uses of electromagnetic waves :

| **Category** \ | **Uses** \ |
| --- | --- |
| gamma rays \ | used to kill the bacteria in marshmallows and to sterilize medical equipment \ |
| X-rays \ | used to image bone structures \ |
| ultraviolet light \ | bees can see into the ultraviolet because flowers stand out more clearly at this frequency \ |
| visible light \ | used by humans to observe the world \ |
| infrared \ | night vision, heat sensors, laser metal cutting \ |
| microwave \ | microwave ovens, radar \ |
| radio waves | radio, television broadcasts |
