What is light?
What is reflection?
What is The process in which light hits a surface and bounces back off that surface.
What is refraction?
What is the bending of light when it travels from one medium to another.
List an example of a concave mirror.
What is a car mirror or other type of concave mirror.
What happens to light when it hits a transparent object?
What is the light passes through with no affect.
What's a natural light source?
What is light that occurs in nature.
What is a plane mirror?
What is a flat reflective surface.
Why does light bend?
What is it bends because it changes speeds when going through mediums with different densitys.
List an example of a convex mirror?
What is a beauty mirror or other type of convex mirror.
What happens when light hits an opaque object?
What is no light goes through.
What is an artificial light source?
What is Light created by us humans.
What is the normal line?
What is the line that divides the angle of reflection and angle of incidence into equal angles.
What happens when light enters a more dense medium then the one it came from?
What is it will slow down and bend towards the line of normal.
What happens to light when it hits something translucent?
What is some light will go through while the rest will be either absorbed or reflected.
What is a phosphorescent light source?
What is light energy is stored and released later.
What is a ray?
What is an imaginary line that represents the path of a beam of light.
How do smooth and rough surfaces reflect light differently?
What is smooth surfaces reflect light uniformly while rough surfaces reflect light in a scattered way.
What happens when light enters a less dense medium then the one it came from?
What is it goes faster and bends away from the line of normal.
What is a chemiluminescent light source?
What is light released by chemical reactions.
What is an incandescent light source?
What is light emitted from heat.
What is a bioluminescent light?
What is light emitted from living things.
What do convex mirrors do?
What is they make images appear smaller and farther away.
What is the angle of refraction?
What is the new direction of light.
What do concave mirrors do?
What is make images appear bigger.
What is a fluorescent light source?
What is when an electrical current causes mercury to vaporize creating ultraviolet energy.
