What is 1 + 3?
The parts where the coils are close together in a longitudinal wave
Change in the apparent frequency of a wave as observer and source move toward or away from each other
Lens such that a beam of light passing through it is brought to a point or focus, lens is thicker in the center
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
The complete range of electromagnetic wave frequencies and wavelengths
Combination of transverse and longitudinal waves. The wave moves from one medium to another. EXAMPLE: ocean waves
The ability to do work
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
The distance between any two crests or compressions next to each other in a wave; SHORTER WAVELENGTH = MORE ENERGY; LONGER WAVELENGTH =LESS ENERGY
This wave travels up and down while the energy travels left and right. ex: water wave, rope wave
Waves that transfer electric and magnetic energy through the vacuum of space.
