Light and Optics

What is reflection?

• The act of thinking deeply about something

• The ability to see your own reflection in a mirror

• The process of bouncing light off a surface

• The ability of a program to examine and modify its own structure, behavior, and state at runtime.

What is refraction?

• The bending of light as it passes from one medium to another due to a change in its speed.

• The reflection of light as it passes from one medium to another

• The scattering of light as it passes from one medium to another

• The absorption of light as it passes from one medium to another

What is absorption?

• The process in which one substance is transformed into another substance.

• The process in which one substance is destroyed by another substance.

• The process in which one substance is released by another substance.

• The process in which one substance is taken up by another substance.

What is transmission?

• Process of transferring emotions

• Process of transferring physical objects

• Process of transferring data or signals

• Process of transferring electricity

When light bounces off a surface, it is called:

• transmission

• absorption

• refraction

• reflection

When light changes direction as it passes from one medium to another, it is called:

• refraction

• absorption

• diffraction

• reflection

When light is taken in and not reflected or transmitted, it is called:

• absorption

• transmission

• reflection

• refraction

When light passes through a material without being absorbed or reflected, it is called:

• transmission
