A wave that moves through some type of matter ex) ocean waves, move through water

Travels perpendicular (at right angles) to the direction of the source's motion

A wave that travels in the same direction as the vibrations that produce it

The matter a wave travels through

The distance between the highest crest and the resting position measures the wave's...

The distance a wave travels before it starts to repeat

The number of times a wave repeats in a given amount of time is called it's...

Transfer energy like a mechanical wave but can move WITHOUT a medium

The wave bounces off and heads in a different direction

The bending of waves due to a change in speed

When waves bend around an object

The energy of a wave is transferred to the material it encounters

Moving from one medium to another

The interaction between waves that meet

A wave that appears to stand in one place, even though it is 2 waves interfering as they pass through each other

The increase in the amplitude of a vibration that occurs when external vibrations match an object's natural frequency

A description of how a sound is perceived as high or low

The amount of energy per second carried by a wave

A unit used to compare the loudness of different sounds

The perception of the energy of a sound

The change in frequency of a wave as its source moves in relation to an observer

Reflection that occurs when parallel light rays hit an uneven surface and all reflect at different angles

A wave that can transfer electric energy through the vacuum of space

The complete range of electromagnetic waves placed in order of increasing frequency

The longest wavelengths and the lowest frequencies. Used for cellphones, internet and other networks

Have a shorter wavelength and higher frequency than radio waves, used in radar to measure speed

Have shorter wavelengths and higher frequencies than infrared, electromagnetic waves that you can see.

Invisible heat

UV rays have higher frequency and carry more energy than visible light

High frequency can go through most objects, used to take pictures of bones

Shortest wavelengths and highest frequencies, greatest amount of energy, can be dangerous, but also used to treat cancer

A material that transmits most of the light, you can see through it like a window

A material that scatters light that passes through it, will create blurry image

A material that reflects or absorbs all of the light that strikes it, cannot see through them

Surface that curves outward

The location at which rays parallel to the optical axis reflect and meet

Surface that curves inward
