Reflection

Bouncing of Light

100

This type of interference makes louder sounds

Constructive, because it is "adding" together the waves to make them higher in amplitude, and sound.

100

Crest

Top of the wave

100

Longitudinal Waves

particles move parallel to the direction which this wave moves, a.k.a. “compression waves”

200

Bending of Light

Refraction

200

Invaded/Venus

Infrared/Visible
200

Noise canceling headphones are an example of what kind of interference?

Destructive because the wave either has no sound (amplitude) or a low sound (amplitude). 

200

Trough

Bottom of a wave

200

Transverse Waves

particles move perpendicular to the direction which the wave moves

300

Diffraction

Spreading out of Light

300

Wavelength

distance between successive parts of a wave (Crest-to-crest or trough-to-trough)

300

Frequency/Period/Wavelength

Frequency: the number of cycles (or oscillations) per second (f unit: Hz 1/sec)

Period: the time it takes for one cycle 

(T unit: seconds)

Wavelength: the distance “crest-to-crest” or “trough-to-trough” (or the distance to complete one full cycle)

(Lambda λ unit: meters)

400
Light Waves vibrating in one plane only

Polarization

400

Guns

Gamma Rays

400

Constructive Interference

When 2 waves meet in-phase and the resulting wave is higher in amplitude. 

400

Amplitude

distance from normal resting position to the top of the crest (or to bottom of the trough)

400

PARTS OF A COMPRESSION WAVE

Compression: an increase in medium density

Rarefaction:  a decrease in medium density





500

Interference

Superposition of 2 or more waves. Constructive or Deconstructive.  

500

LOW E --> HIGH E (visible colors)

Red-->Violet (R O Y G B I V)

500

Destructive Interference

When 2 waves meet out-of-phase and the resulting wave is lower in amplitude. 

500

Node/Antinode

Node: point of zero amplitude; rest position

Antinode: point of maximum amplitude; is the 

crest / trough
