Across
- The separation of polychromatic light in to its component wavelengths or colors (makes a rainbow)
- If light enters a second medium at this angle, it will never bend.
- The length of a single cycle
- Point on a standing wave where the energy is smallest
- This type of wave cannot travel through a vacuum
- When a pulse reaches a fixed boundary it reflects and _____
- When there is a 180 degree difference between two waves, we say they are completely _____ of phase.
- This kind of interference occurs when a crest meets a trough
- This color gets bent or refracted the most in a prism.
- Every electromagnetic wave on your reference table travels at the ______________ of light in a vacuum
- Determines loudness of a wave
- IF A FAST MOVING STAR MOVES TOWARDS THE EARTH ITS COLOR WILL SHIFT TOWARDS THIS PART OF THE SPECTRUM
- The time it takes for a single wave to pass. (inverse to freq)
- IF A FAST MOVING STAR MOVES AWAY from THE EARTH ITS COLOR WILL SHIFT TOWARDS THIS PART OF THE SPECTRUM
- In this type of wave, the vibration is perpendicular to the direction the wave travels.
- AS THE FREQUENCY OF A WAVE INCREASES ITS WAVELENGTH
- The filtering of light due to its orientation
- A wave with a frequency of 1 x 10^8 Hz (see ref.)
- In refraction problems we always measure our angle with respect to the _____________ (hint - dotted line)
- This speed of a wave is determined by the ____________

Down
- The change in the observed frequency of a wave when there is relative motion between the source and receiver of a wave. _________ effect
- THE COLOR OF A LIGHT WAVE WITH A FREQUENCY OF 5 X 10^14 HZ
- The third slowest color in glass.
- When the vibration of one object causes the vibration of another object.
- This kind of interference occurs when a trough meets a trough
- In this type of wave, the vibration is parallel to the direction the wave travels.
- Unit of frequency
- Point on a standing wave where the energy is greatest
- This kind of reflection does not produce an image
- A series of evenly timed vibrations produce a _______ wave.
- This electromagnetic wave has a lower frequency than visible light and higher frequency than radio waves
- Law of Reflection - Angle of ________ equals the angle of reflection
- This kind of reflection produces an image
- The spreading out of a wave in to a region beyond a boundary or opening. Proves light is a wave.
- This wave term has no units - _________ of refraction
- RELATIONSHIP BETWEEN FREQUENCY AND WAVELENGTH IS
- When waves of the same frequency and amplitude traveling in opposite directions meet, a ____________wave is produced.
- The larger the index of refraction (n), the __________the medium
- This property of a wave does not change when light refracts
