Electromagnetic radiation is... | A form of energy that exhibits wavelike behavior as it travels through space. |
Visible light is... | Type of electromagnetic radiation. |
Wavelength | The shortest between equivelent points on a continous wave. |
How is wavelength measured? | From crest to crest. From trough to trough. |
Frequency | The number of waves that pass a given point per second. |
One hertz | The SI unit of frequency. |
Amplitude | The waves height from the origin to a crest or from the orgin to the trough. |
The speed of all electromagnetic wave is.. | The same |
As one quantity increases the other... | Decrease |
Sunlight is an example of | Whitelight |
Encompasses all forms of electromagnetic radiation with the only differences in the types of radiation being their frequencies and wavelengths | Electromagnetic spectrum |
Matter can gain or lose energy only in small specific amount called | Quanta |
Quantum | The minimum amount od energy that can be gained or lost by an atom |
Photoelectric effect | Electrons called photoelectrons are emitted from a metals surface when light of a certain frequency shines on the surface |
Photon | A particle of electromagnetic radiation with no mass that carries a quantum of energy |
Atomic emission spectrum | The set of frequencies of the electromagnetic waves emitted by atoms of the element |
