Unit 5
Term | Definition |
---|---|
amplitude | The height of a wave from rest to crest or from rest to trough |
crest | The highest point of a wave. |
energy | The ability to do work. Waves carry energy from one location to another. |
evidence | Information that explains or supports a claim. |
frequency | The number of times something repeats within a fixed period such as number of cycles per second. |
pattern | Something that is repeated over and over. |
reflection | The return of waves from a surface. |
trough | The lowest point of a wave. |
wave | A disturbance that travels through space or matter transferring energy from one place to another. |
wavelength | The distance between two corresponding points on a wave. |
electromagnetic radiation | A form of energy that is all around us including radio waves visible light and X-rays. |
medium | Any substance that waves move through |
opaque | The property of blocking out all light. Light shining on an opaque object creates a shadow. |
electromagnetic spectrum | The range of electromagnetic radiation that is all around us such as radio waves visible light and X-rays. |
light | The form of energy or electromagnetic radiation that makes it possible to see things. |
scientific inquiry process | A process that scientists use to explore observations and answer questions. |
visible spectrum | The part of the electromagnetic spectrum that people can see. It contains red, orange, yellow, green, blue, indigo, and violet light. |
refraction | The bending of rays or waves as they pass from one medium to another. |
translucent | The property of allowing some light to pass through. You cannot see completely through a translucent object. |
transparent | The property of allowing almost all light to pass through. You can see through a transparent object. |
