|---|---|---|---|---|---|
| ELECTROMAGNETIC RADIATION | a kind of radiation including visible light, radio waves, gamma rays, and X-rays, in which electric and magnetic fields vary simultaneously.
🗑
|
||||
| Electromagnetic Spectrum | the range of wavelengths or frequencies over which electromagnetic radiation extends.
🗑
|
||||
| Wavelength | the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.
🗑
|
||||
| Frequency | he rate at which a vibration occurs that constitutes a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light), usually measured per second.
🗑
|
||||
| Photoelectric Effect | The photoelectric effect refers to the emission, or ejection, of electrons from the surface of, generally, a metal in response to incident light
🗑
|
||||
| Quantum | a discrete quantity of energy proportional in magnitude to the frequency of the radiation it represents.
🗑
|
||||
| Photon | a particle representing a quantum of light or other electromagnetic radiation. A photon carries energy proportional to the radiation frequency but has zero rest mass.
🗑
|
||||
| Ground State | the lowest energy state of an atom or other particle.
🗑
|
||||
| Excited State | excited state can commonly take the form of the electron jumping from its original energy level or orbital, also known as the ground state, to an empty orbital of a higher energy shell that is further away from the nucleus.
🗑
|
||||
| Line Emission Spectrum | When an electric current passes through a gas, it gives energy to the gas. This energy is then given out as light of several definite wavelengths (colours). This is called a line emission spectrum.
🗑
|
||||
| Continuous Spectrum | an emission spectrum that consists of a continuum of wavelengths.

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.
