what are the three rules of light?
well one of them is that it can't bend. it always travels straight.
1) Bright light will damage your eyes. 2) Light let's you see things. 3) Light things are easier to lift than heavy things.
There are a few general properties to know about light 1. Light has an intensity that can be measured [candelas?] 2. Light has a specific frequency or wavelength, which can be related to each other with the equation v=lambda(f) -v = velocity of the light [m/s] -lambda = the wavelength [m] -f = frequency [Hz] or [Inverse seconds (s^-1)] 3. Wave - particle duality of light -light can behave as a wave with a specific wavelength, or as a particle there are probably more but that's a start
three of the rules: (a) light travels in a straight line; (b) the farther you are from a light source, the dimmer the light; and (c) the angle that a light beam makes when it hits a mirror (the angle of incidence) is the same size as the angle the beam makes when it bounces off the mirror (the angle of refraction).
