|---|---|---|---|---|---|
| Compressional wave | A shock wave that compresses the medium through which it is transmitted. Also, compressional wave. Compare expansion wave.
🗑
|
||||
| diffraction | Change in the directions and intensities of a group of waves after passing by an obstacle or through an aperture whose size is approximately the same as the wavelength of the waves.
🗑
|
||||
| electromagnetic spectrum | The entire range of radiation extending in frequency from approximately 1023 hertz to 0 hertz or, in corresponding wavelengths, from 10-13 centimeter to infinity and including, in order of decreasing frequency, cosmic-ray photons, gamma rays, x-rays, ultr
🗑
|
||||
| frequency | Also, fre·quence. the state or fact of being frequent; frequent occurrence: We are alarmed by the frequency of fires in the neighborhood.
🗑
|

| infrared waves | a wave with a frequency between 300 GHz and 400 THz
🗑
|
||||
| intensity | Physics The amount or degree of strength of electricity, light, heat, or sound per unit area or volume.
🗑
|
||||
| pitch | Any of various thick, dark, sticky substances obtained from the distillation residue of coal tar, wood tar, or petroleum and used for waterproofing, roofing, caulking, and paving.
🗑
|
||||
| refraction | Refraction is the bending of light as it passes from one substance to another. Here, the light ray passes from air to glass and back to air.
🗑
|
||||
| reverberation | Having a tendency to reverberate
🗑
|
||||
| transverse wave | a wave in which the direction of displacement is perpendicular to the direction of propagation, as a surface wave of water.
🗑
|
||||
| ultraviolet waves | Ultraviolet rays. Invisible light rays with a wavelength shorter than that of visible light but longer than that of x rays.
🗑
|
||||
| wave | The most important part of this definition is that a wave is a disturbance or variation which travels through a medium.
🗑
|
||||
| wavelengh | The distance between one peak or crest of a wave of light, heat, or other energy and the next.
🗑
|
||||
| amplitude | the state or quality of being ample, especially as to breadth or width; largeness; greatness of extent.

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
