Wave interference
Light Waves
100

A wave whose oscillations are perpendicular to the direction of the wave's advance. Ex. Vibrations in a guitar string.

What is a Transverse Wave?



100

The highest part of a wave

What is a Crest?


100

The interference or bending of waves around the corners of an obstacle or through an aperture into the region of geometrical shadow of the obstacle/aperture

Diffraction



100

the combination of 2 or more electromagnetic wave forms to form a resultant wave

Interference 

100

the angle between a reflected ray and the normal drawn at the point of incidence to a reflecting surface

What is Angle of Refraction?


200

Waves in which the vibration of the medium is parallel to the direction the wave travels and displacement of the medium is in the same direction of the wave propagation. Ex. Seismic P-Waves

What are Longitudinal Waves?



200

The lowest part of a wave

What is a Trough?



200

The redirection of a wave as it passes from one medium to another.

Refraction


200

when two waves of identical wavelengths are in phase, they form a new wave with an amplitude equal to the sum of their individual amplitudes

Constructive interference 

200

the angle between an incident ray and the perpendicular to the surface

What is the Angle of Incidence?


300

A wave that is an oscillation of matter. Ex. Stadium Waves

What is a Mechanical Wave?



300

The time to complete one cycle.

What is a Period?



300

Include information for both light and sound -  the change in frequency of a wave in relation to an observer who is moving relative to the wave source.

Doppler Effect


300

when the maxima of two waves are 180 degrees out of phase

Destructive interference 

300

reflection of light or other waves or particles from a surface such that a ray incident on the surface is scattered at many angles rather than at just one angle as in the case of specular reflection.

What is Diffuse Reflection? 


400

A wave that oscillates in time but whose peak amplitude profile does not move in space. Ex. Notes on strings instruments

What is a Standing Wave?



400

A point along a standing wave where the wave has minimum amplitude.

What is a Node?


400

The change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated.

Reflection


400

the pulsation caused by the combination of two waves of slightly different frequencies

Beats 

400

a ray of light that strikes a surface

What is an Incident Ray?


500

A wave in which the particles of the medium move progressively in the direction of the wave propagation with the faster speed overtaking the slower speed. Ex. Water waves

What is a Traveling Wave?



500

A region of maximum amplitude situated between adjacent nodes in a vibrating body.

What is an Antinode?



500

Regular variation in magnitude or position around a central point.

Oscillation



500

the phenomenon of increased amplitude that occurs when the frequency of an applied periodic force is equal or close to a natural frequency of the system on which it acts

Resonance 

500

on reflection from a smooth surface, the angle of the reflected ray is equal to the angle of incident ray

What is the Law of Refraction?
