Lasers

Question 1

What is the order of wavelengths on the electromagnetic spectrum, and which are ionizing and non-ionizing?

Where do lasers fit in this spectrum (ionizing or non-ionizing)?

Answer 1

largest wavelengths to smallest wavelengths:
Non-ionizing
-Radio waves
-Microwaves
-Infrared waves
-Visible light (red 740nm through to violet 380nm)
-Ultraviolet waves
Ionizing
-Ultraviolet waves
-x-rays
-Gamma rays
* the largest of the UV wavelengths are not ionizing.

2. Lasers are non-ionizing
