Light is just part of a continuum of waves called the electromagnetic spectrum. This spectrum includes many types of wave that you will recognize including X-rays and infra-red.
Properties, Dangers and Uses
The properties dangers and applications of the varies waves on the em spectrum are in the table below.
||Internal heating of body tissue|
||Strong light causes damage to vision.|
||Skin cancer and blindness|
||Mutations in cells and severe burns to the skin.|
||Cancers and cell mutation|
Questions and Answers
Hi Jamie, What why is electromagnetic wave called electromagnetic?
Just a confusion I have with understanding this. light isn't electric or magnetic. Just a curious mind. thinking why it is chosen to be named this way.
Electromagnetic wave means a wave that can propagate because of the periodic variation of the intensities of both the electric and magnetic fields.In other words, it means, when the intensities of the electric and magnetic fields change periodically, the wave can propagate. It doesn't mean that light (an example of electromagnetic wave) should be magnetic or electric.
What are the uses and dangers of the electromagnetic spectrum?
The x-ray above is one of the MANY THAT SOME PEOPLE HAVE TAKEN.
