The parts where the coils are close together in a longitudinal wave
Doppler Effect
Change in the apparent frequency of a wave as observer and source move toward or away from each other
Convex Lens
Lens such that a beam of light passing through it is brought to a point or focus, lens is thicker in the center
Concave Lens
A lens that is thinner in the center than at the edges, a lens such that a parallel beam of light passing through it is caused to diverge or spread out
Electromagnetic Spectrum
The complete range of electromagnetic wave frequencies and wavelengths
Surface Waves
Combination of transverse and longitudinal waves. The wave moves from one medium to another. EXAMPLE: ocean waves
The ability to do work
Speed=Wavelength xFrequency,Frequency=Speed/Wavelength,
Is the number of complete waves that pass a given point in a certain amount of time
Longitudinal (Compressional) Wave
The wave travels in the same direction as the disturbance
The maximum height of a wave from its rest position;LARGE AMPLITUDE = MORE ENERGY; SMALL AMPLITUDE = LESS ENERGY
Wave Length
The distance between any two crests or compressions next to each other in a wave; SHORTER WAVELENGTH = MORE ENERGY; LONGER WAVELENGTH =LESS ENERGY
Transverse Wave
This wave travels up and down while the energy travels left and right. ex: water wave, rope wave
Electromagnetic Waves
Waves that transfer electric and magnetic energy through the vacuum of space.
An empty area or space
