The electromagnetic spectrum describes the full range of light that is generally divided into ________ regions of wavelength and in the order of increasing energy and frequency.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Seven.
- Electromagnetic radiation spans an enormous range of wavelengths and frequencies. This range is known as the electromagnetic spectrum, according to UCAR (opens in new tab).
- The electromagnetic spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency.
- Electromagnetic radiation is a type of energy that is all around us and takes many forms, such as radio waves, microwaves, X-rays and gamma-rays.
