The correct answer is X-Ray.
- Electromagnetic (EM) radiation includes radiation via radio waves, microwaves, X-rays and gamma rays.
Key Points
- Electromagnetic (EM) radiation is a form of energy that is all around us and takes many forms.
- Electromagnetic (EM) radiation includes radiation via radio waves, microwaves, X-rays and gamma rays.
- Sunlight is also a form of EM energy.
Additional Information
- EM radiation spans an includes a range of wavelengths and frequencies.
- This range is known as the electromagnetic spectrum.
- The EM spectrum is generally divided into seven regions:
- Radio waves,
- Microwaves,
- Infrared (IR),
- Visible light,
- Ultraviolet (UV),
- X-rays,
- Gamma rays.
