| Question | Answer |
|---|---|
| Concave Mirror | curves inward like inside a bowl and rays converge (come together)as they bounce back. |
| convex mirror | curves outward and light rays spread out as they bounce back. |
| Transparent | materials that transmit all light. Light goes through them |
| Translucent | materials that scatter the light as it passes through them |
| Plane Mirror | a mirror that is flat |
| Refraction | Light moving from one transparent material to another undergoes a change in direction |
| Refelction | The law of reflection states that the angle of an incoming ray of light and the angle of the reflected light are always equal. |
| Evidence of waves | Interference and polorization provide evidence that light is a wave. |
| Luminous | Something that produces light. |
| Opaque | material reflects or absorbs all light |
| transmitted | When light passes right through an object |
| reflected | When light bounces off an object |
| absorbed | When light is taken in or trapped by an object |
| refracted | When light rays enter a new medium at an angle, the change in speed causes them to bend |
| Incandescent | When visible light is given off at high tempatures |
| electromagnetic wave | Electromagnetic waves are formed when an electric field couples with a magnetic field |
| Black body radiation | idealized material that perfectly absorbs and perfectly emits electromagnetic radiation. |
| Consistent law principle | The laws of physics are the same in all referance frames that are moving at a constant velocity with respect to one another. |
| Consistancy of speed principle | The speed of light in empty space has the same valur for all obnservers regardless of their velocity |
| index of refraction | The ratio of c to the speed of light in some transparent material v |
| interference of light | |
| virtual image | |
| Angle of incidents | Equals angle of reflection 0i=0r |
| index of refraction | speed of light in vacumm/speed of light in material n=c/v |
| speed of light in a vacuum | (wavelength)(frequency) c=kf |
| Energy of photon | (Planks constant)(Frequency) E=hf |
| photoelectric effect | |
| Photon | |
| total internal reflection | |
| quanta | |
| unpolorized light | |
| real image | |
| light ray model |
