waves
Term | Definition |
---|---|
Absorption -the transfer of energy from an wave to a medium. | Echo - a repeated sound that is caused by the reflection of a sound wave from a surface. |
Amplitude - the distance between the highest crest and the resting position. | Electromagnetic wave - a form of energy that can travel through empty space. |
Barrier - something that blocks the way an obstacle. | Frequency - the number of time a wave repeats in a given amount of time. |
bend - to turn or force from straight or even to curved or angular. | Lens - a curved piece of glass or plastic designed to refract light in a specific way. |
brightness -the lightness or darkness of reflected light | Light wave -waves the come from a light source . |
color - what you see when light shines | matter - anything that has mass and take up space. |
color filter -a transparent material the absorbs some colors and allows others to pass through. | Mechanical wave - a wave that requires a medium to travel tho |
medium media - material through which a wave travels | mirror - a reflecting surface. |
path - also known as trajectory is the path an object follows in space | prism -a piece of glass or transparent material that bends light |
propagate- the way waves travel or move | proportion- something changes with regard to something else |
ray - the movement of light from its source to a surface or object. | ray diagram - show how light travels including what happens when it reaches a surface |
reflection - waves bouncing off a medium | refraction refracted - the bending of wave due to a change in speed |
sound wave - a vibration or wave the travels through matter | transmit- to cause (light heat sound ) to pass through a medium |
transparent allows light to pass through a medium | visible light spectrum - the portion of the electromagnetic spectrum the human eye can |
wave- any disturbance the transfers energy from place to place | wavelength - the distance the wave travels before it starts to repeat. |
