The type of interference that occurs when the two waves are in antiphase. When one wave is at a peak and one is at a trough their addition results in a minimum point
Back
Card 7
Front
The spreading of waves as they pass through a gap of a similar magnitude to their wavelength
Back
Card 8
Front
The distance that a point on a wave is from its equilibrium position
Back
Card 9
Front
The spectrum of electromagnetic waves, consisting of Gamma rays, X rays, Ultraviolet, Visible light, Infrared, Microwaves and Radiowaves
Back
Card 10
Front
Waves that consist of perpendicular electric and magnetic oscillations. All electromagnetic waves travel at the speed of light in a vacuum
Back
Card 11
Front
The number of waves that pass a point in a unit time period. It is the inverse of the time period
Back
Card 12
Front
The oscillation of a wave at its natural frequency
Back
Card 13
Front
The power transferred per unit area. It is proportional to the square of a wave's amplitude
Back
Card 14
Front
The superposition of the amplitudes of waves when they meet
Back
Card 15
Front
A wave with oscillations that are parallel to the direction of energy propagation. Sound waves are an example of a longitudinal wave. They cannot travel through a vacuum
