Light and Optics Quizs

Dispersed light

• Process of white light splitting into its constituent colors (red, orange, yellow, green, blue, indigo, violet).

• A phenomenon where light is absorbed by a surface and not reflected.

• The scattering of light in different directions due to particles in the atmosphere.

• The bending of light as it passes through different mediums.

Transmit

• When light hits an object and goes through.

• When light is absorbed by an object.

• When light is reflected off an object.

• When light is scattered in different directions.

Reflect

• When light is absorbed by an object.

• When light bounces off an object without absorbing.

• When light is scattered in different directions.

• When light passes through an object without any change.

Refract

• Light changes direction or bends as it goes from one substance to another.

• Light travels in a straight line without changing direction.

• Light is absorbed by a substance and does not pass through.

• Light is reflected off a surface without entering another medium.

Light Source

• An object that gives off light. Example: lamps.

• A device that absorbs light and converts it into heat.

• A material that reflects light without emitting it.

• An object that produces sound waves.

Medium

• A substance that light goes through or tries to go through; light changes speed when this occurs.

• A type of wave that does not require a medium to travel.

• A measure of the intensity of light in a given area.

• A device used to amplify light signals.

Prism

• A solid object that reflects light without color separation.

• A triangular glass with refracting edges separating white light into a spectrum of colors.

• A device that absorbs light and converts it into heat.

• A cylindrical lens that magnifies objects.

Luminous

• Full of light; shining bright.

• Dark and gloomy.

• Dull and colorless.

• Flickering and unstable.

Opaque

• An object/medium that does not allow light to pass through.

• A transparent object that allows light to pass through.

• An object that reflects all light without absorption.

• A translucent object that partially allows light to pass through.

Normal angle of light

• A ray of light hitting a surface at a 90° angle.

• A ray of light hitting a surface at a 45° angle.

• A ray of light hitting a surface at a 30° angle.

• A ray of light hitting a surface at a 60° angle.
