Energy |
Absorption is the transfer of. By a wave to the medium through which it travels |
|
|
Material |
One factor that affects the amount of energy absorbed is the. In which a wave moves |
|
|
Electromagnetic |
All materials absorb. Waves |
|
|
Transmission |
Is the passage of light through an object |
|
|
Reflection |
The bouncing of a wave off a surface |
|
|
White |
Objects that reflect all visible light appear |
|
|
Black |
Objects that do not reflect any visible light appear |
|
|
Same angle |
The angle at which a wave can be. When they hit a surface |
|
|
Perpendicular |
The normal is an imaginary line that is. To a surface |
|
|
Incidence |
The angle of. Is equal to the angle between the normal and an incoming wave |
|
|
Reflection |
The angle of. Is equal to the angle between the normal and outgoing wave |
|
|
Equal. Law of reflection |
The angle of an incidence and the angle of reflection are. ________ this is called the ___________ |
|
|
Reflected |
All types of waves can be _________ when they hit a surface |
|
|
Direction |
Refraction occurs when a wave changes. Because it's speed changes |
|
|
More |
The greater the change in speed is the. The wave changes direction |
|
|
Diffraction |
The change in direction of a wave when it travels by the edge of an object or travels through an opening is called |
|
|
Sound |
Waves spread out as they travel through a doorway because their wavelengths are roughly the same width as the diorway |
|
|
Light |
The wavelengths of. Waves are more than a million times smaller than the width of a doorway As a result these waves do not spread out as they travel through a doorway |
|
|
Overlap |
Interference occurs when waves. To form a new wave |
|
|
Constructive |
Interference occurs when a crest overlaps a crest or a trough overlaps a trough |
|
|
Destructive |
Interference occurs when a crest overlaps a trough |
|
|
Standing |
A. Wave can form when two waves with the same wavelength overlap while they are traveling in opposite directions |
