Wave:A disturbance or oscillation that travels through space and matter, accompanied by a transfer of energy
Frequency:The number of peaks that go by in a second, or cycles per second
Hz:the SI unit of frequency defined as the number of cycles per second of a periodic phenomenon
Ultraviolet:Bees can see ______(kind of light), but people can’t
velocity:_____= frequency x wave length
Amplitude:The “size” of the wave, for water waves this would be how high the wave goes above still water
Intensity:Equals to Power over Area
Diffraction:Refers to various phenomena which occur when a wave encounters an obstacle
interference:A phenomenon in which two waves superimpose to form a resultant wave of greater or lower amplitude
Resonance:The most spectacular effect of waves is ______ where a wave is reflected back and forth and driven at the proper frequency
Angstrom:A unit of length equal to 0.1 nm
Atomic:______ diameter = about two Angstroms or 0.2 nm
Visible:By definition if we can see it it is _____!
Alpha:_____ rays are a combination of two protons and two neutrons, a He4 nucleus
Positrons:_____are antimatter electrons! Medically they are used for detecting cancer etc. in somewhat the same way as other nuclear decays
Proton:Found in the nucleus or atom
Molecule:Water is a(n) ________while hydrogen and oxygen are atoms
Atom:A(n) _____ is sometimes pictured as being like a solar system
Electron:Has a negative charge
Columns:If electrons could spin up, down, and sideways there would be more _____ in the periodic table
