Electromagnetic Spectrum
20
Radiation: Is the range of all possible frequencies of electromagnetic ____
Radio: Low frequencies can be used for ____ communication
Short: High frequencies have a ____ wavelength
High: Short wavelengths have ____ energy
Long: Low frequencies have a ____ wavelength
Low: Long wavelengths have ____ energy
Spectroscopic: Most parts of the electromagnetic spectrum are used in science for ____ interactions as a way to characterize samples
Microwaves: They will cook your popcorn or melt your media in minutes
Infrared: Night vision goggles detect this being emitted from the skin or other objects
Ultraviolet: The sun is a source of this and it is because of this that we get sun burns
Xrays: You can use these to look at bones or teeth
Gamma: These rays can be emitted from radioactive materials (some natural, others man-made like in nuclear power plants)
Visible: This part of the spectrum is the only part we can see with our eyes
Frequency: Typically measured in hertz, this is the number of occurrences of a repeating event in a given time
Red: The colour with longest wavelength
Violet: The colour with the shortest wavelength
Speedoflight: All electromagnetic waves travel at this (3 words)
Photons: The tiny packets of energy given off as electromagnetic radiation are called ____ and can be either particles or waves
Tiny: Visible waves are a ____ portion of the spectrum
Herschel: The first discovery of electromagnetic waves other than light came in 1800 when William ____ discovered infrared light
