How light behaves at a boundary By Victoria Skinner

17.1 How Light law of reflection *If 2 parallel beams strike a mirror 2 reflected beams are also parallel *If a line is perpendicular to a mirror it is the normal because it is normal to the surface.

reflections *regular reflection- happens when light is reflected back to the observer in parallel beams *Diffuse reflection- the scattered, fuzzy reflection from a rough surface where light is reflected Refraction of light

Angle of refraction Angle of refraction- the angle the refracted ray makes with the normal to the surface Optically dense Optically dense- materials with larger indices of refraction with respect to other materials

Snells law *Snell's law- states that the ratio of sine of the angle of refraction is a constant Incident Ray traveling in a less dense medium index of refraction *index of refraction- the ratio of the speed

of light in a vacuum to its speed in a material * *The index of refraction often can be measured by directing a ray of light onto the substance's surface, measuring the angle of incidents and angle of refraction,then using Snells law .

. problem solving strategies 1.draw a diagram showing 2 media and label 2. Draw the incident ray 3.use protractor

4.use Snells law 5.use protractor 6.evaluate. *when solving problems involving refractions and reflections of light a one will use a ray diagram . * when setting up a Snell's law problem assign symbols for the various quantities, and check your results.
