1 our skin emits light, which is why we can be seen in the dark using a night vision gogles 2 radiation which our eyes can see (ex. emitted from fireflies; to light bulb) 3 sun is source of these rays that cause sunburn 4 use to look at bones 5 radioactive materials emit these rays. The most energetic of all rays. Very short wavelength.	1 INFRARED (IR) 2 VISIBLE (VIS) 3 ULTRAVIOLET (UV) 4 X- RAYS 5 GAMMA RAYS
Visible Light Colors	ROYGBIV red, orange, yellow, green, blue, indigo, and violet
1 radiation that can be stopped by a paper 2 radiation than can penetrate paper but stopped by GLASS OR ALUMINUM 3 Radiation that can penetrate paper and glass but stopped by CONCRETE, LEAD OR STEEL	1 Alpha radiation 2 Beta radiation 3 Gamma radiation
Can be described in terms of stream of PHOTONS, which are massless particles each travelling in a wavelike pattern and moving at the speed of light	ELECTROMAGNETIC RADIATION (ER)
White light (RE) transmitted and absorbed by __	CuSO4
In the CuSO4 solution: 1. The intensity of transmitted radiant energy is related to the concentration of the solution which absorbs the RE 2. If the concentration of soln is ↑ - intensity of color of soln is ↑ 3. If the concentration of the son is ↓ - intensity of color of soln is ↓	.
