1. the number of complete oscillations that a wave makes each second
2. the difference between the observed wavelength of light and actual wavelength of light based on the relative speed of the observer and the source of the light.
3. a spherical lens defect in which light passing through a lens is focused at different points, causing an object viewed through a lens to seem to be ringed with color
4. the low point of a wave
5. a wave that strikes a boundary between two media

5 Matching Questions

4. closed-pipe resonator
5. constructive interference

1. a point where incident light rays that are parallel to the principle axis coverage after reflecting from the mirror
2. b a medium that transmits light and also can reflect a fraction of the light, but doesnt allow objects to be seen clearly through it.
3. c a single disturbance or pulse that travels through a medium
4. d a resonating tube with one end closed to air; its resonant frequencies are odd-numbered multiples of the fundamental
5. e a type of interference which occurs at any location along the medium where the two interfering waves have a displacement in the same direction.

5 True/False Question

1. diffuse reflection → the angle of incidence is equal to the angle of reflection
   

   True        False

2. polarized → the property of electromagnetic waves, such as light, that describes the direction of the electric field.
   

   True        False

3. opaque → a disturbance that carries energy through matter or space; transfers without transferring matter.
   

   True        False

4. convex mirror → reflects light from its INWARDLY curving surface and can produce either an upright, virtual image or an inverted, real image.
   

   True        False

5. laser → (light amplification by stimulated emission of radiation) device that produces powerful, coherent, directional, monochromatic light that can be used to excite other atoms.
   

   True        False
