Motions, Forces, and Energy
Question | Answer |
---|---|
This is when light energy strikes an object and is changed to heat energy. The process of retaining radiation without reflecting it. | absorption |
In a transverse wave, this is the magnitude of height of a wave from origin to crest. In a longitudinal wave, this is corresponds to how much the wave is compressed, as compared to areas of little compression. | amplitude |
The place of maximum displacement on a standing wave. | antinode |
This is the color of objects that do not reflect light from any part of the visible spectrum; they absorb all frequencies of visible light. | black |
Also called a longitudinal wave, they are waves whose direction of vibration is the same as their direction of travel.They produce compression and rarefaction when traveling through a medium. | compression wave |
This is a lens that has at least one surface that curves inward | concave lens |
This is a lens which is thicker in the middle than on the ends. It refracts parallel light rays so they come together at a single point, called the focal point. | convex lens |
Mirror that is a reflecting surface that bulges inward or away from the incident light. Such mirrors reflect light inward to one focal point and can produce a real image. | concave mirror |
Mirror that is a reflecting surface in which the reflective surface bulges toward the light source. Such mirrors reflect light outwards and always form a virtual image. | convex mirror |
This is a measure of sound pressure level. | decibel |
This is a measure of mass per unit volume. | density |
This is a geologic event that occurs when tectonic plates are shifted violently. | earthquake |
The complete range of light waves organized by wavelength/frequency. | electromagnetic spectrum |
A propagating wave in space with electric and magnetic components. These components oscillate at right angles to each other. It may travel in a vacuum. | electromagnetic wave |
This is the number of complete movements of a wave per second. | frequency |
This is anything with mass that occupies space. | matter |
This is the material in which a mechanical wave travels. | medium |
The place on a standing wave where no motion occurs due to destructive interference | node |
This is any material that allows no light waves to be transmitted through. Light waves are either absorbed or reflected. | opaque |
This is a type of electromagnetic wave used for communications and Astronomy. | radio wave |
The bouncing back of a wave from a surface. | reflection |
This is any material that transmits some light, but causes the light to be scattered so no clear image is seen. | translucent |
This is any material that that transmits most of the light that strikes to pass through and only a small amount of light is reflected or absorbed. | transparent |
This is the distance from the peak to a peak of a successive wave. | wavelength |
As wavelength increases, frequency _______________________ | decreases |
The higher the frequency, the ___________________ the energy | higher |
A wave which needs a medium (solid, liquid, gas) in order to propagate itself | mechanical |
