Unit 2 Module 2 Vocab Quiz

light

• law that states that when a wave is reflected from a surface, the angle of reflection is equal to the angle of incidence
• energy carried by an electromagnetic wave
• the point where light rays parallel to the optical axis converge after being reflected by a mirror or refracted by a lens
• electromagnetic radiation that you can see

radiant energy

• law that states that when a wave is reflected from a surface, the angle of reflection is equal to the angle of incidence
• energy carried by an electromagnetic wave
• the point where light rays parallel to the optical axis converge after being reflected by a mirror or refracted by a lens
• electromagnetic radiation that you can see

transparent

• a material that allows most of the light that strikes it to pass through, but through which objects appear blurry
• a material through which light does not pass
• a material that allows almost all of the light striking it to pass through, and through which objects can be seen clearly

virtual image

• an image of an object that your brain perceives to be in a place where the object is not
• an image that forms where rays converge
• the change in direction of a wave as it changes speed in moving from one medium to another
• a transparent object with at least one curved side that causes light to change direction

real image
