The Electromagnetic spectrum

HideShow resource information
What are electromagnetic radiations?
Electromagnetic radiations are electric and magnetic disturbances. They travel as waves and move energy from place to place.

Do electromagnetic waves travel through a vacuum?
All electromagnetic waves travel through a vacuum (e.g. space) at the same speed
2 of 8
What is the electromagnetic spectrum?
All of the waves together are called the electromagnetic spectrum.

Does the electromagnetic spectrum stop?
The electromagnetic spectrum is continuous.
5 of 8
How are different wavelengths reflected, absorbed or transmitted?
Different Wavelengths of the electromagnetic spectrum are reflected, absorbed or transmitted differently by different substances and types of surface
6 of 8
The [what] the frequency of an electromagnetic wave, the more energy it transfers?
The higher the frequency of an electromagnetic wave, the more energy it transfers
