Type of wave where the particles move perpendicular to the movement of the energy.
Contains Crests and Troughs

Definition
| The number of waves that pass a certain point in 1 second. |
|
|
Term
|
Definition
The maximum displacement of a particle in a wave
When you increase in a sound wave, the volume increases |
|

Term
|
Definition
Something the energy in a wave travels through
Ex: air, water, land |
|

Term
|
Definition
Waves travel through very thin slits. They bend around the slits and can separate wavelengths of light.
(Rainbow filter) |

Term
|
Definition
A lens in which the light is focused at one point. The middle of the lens is thicker than the top and bottom.
Can create a real image if the object is farther than 1 focal length from the lens. |

Definition
| When a wave reflects off a surface, it reflects at the same angle at which it hits the surface in relation to the normal line (a perpendicular line) |
|
|
Term
| Constructive Interference |
|
Definition
When two waves interact with each other and the amplitude increases.
In light waves = brighter
In sound waves = louder |
|
|
Term
|
Definition
When an object emitting a sound and the object hearing the sound are not moving at the same velocity.
As the objects move towards each other, the pitch/frequency increases.
As the objects move apart, the pitch/frequency decreases. |

Definition
| Vibrations (sound waves) are collected by the pinna, travel down the auditory canal, vibrate the eardrum (tympanic membrane), the vibrations are transmitted through the ossicles and is transmitted to the brain via the cochlea. |

Term
|
Definition
One full cycle of a wave
Must include 1 full crest and 1 full trough
OR
1 compression and 1 rarefaction |
|
|
Term
|
Definition
| As waves change medium, they change speed. When they change speed, they bend. |
|
|
Term
|
Definition
Type of wave where the particles move parallel to the movement of the energy.
Contain compressions and rarefactions. |
|
|
Term
|
Definition
A lens in which the light is scattered. The middle of the lens is thinner than the top and bottom.
Always creates a virtual image. |
|
|
Term
|
Definition
The frequency of a sound wave.
High frequency= high pitch
Low frequency = low pitch |
|
|
Term
|
Definition
When two waves interact and the amplitude decreases.
Sound waves = quieter
Light waves = darker |

Creating coherent waves.
Only waves traveling in one direction are allowed to pass through a polarized filter. |
