Flashcards
Progressive Waves
Cards in this deck (11)
- 1Define a progressive wave.A wave that transfers energy (1) without transferring material (2)
- 2Define the amplitude of a wave. (+ units)A wave's maximum displacement from the equilibrium position.
Units: metres (m) - 3Define the frequency of a wave. (+ units)The number of oscillations that pass a fixed point per second.
Units: Hertz (Hz) - 4Define the wavelength of a wave. (+ units)The distance between 2 adjacent peaks or troughs of a wave.
Units: metres (m) - 5Define phase. (+ units)The position of a point on a wave cycle.
Units: degrees, radians, fractions of a wave cycle - 6Define phase difference. (+ units)The difference in position of two points/waves in their cycle
Units: degrees, radians, fractions of a wave cycle - 7Define the period of a wave. (+ units)The time taken for one full oscillation.
Units: seconds (s) - 8What does it mean for two points on a wave to be "in phase"?They are on the same position of a wave cycle, phase difference is a multiple of 360 degrees.
- 9What does it mean for two points on a wave to be in "anti-phase"?They have a phase difference of 180 degrees.
- 10What is the equation for wave speed?c = λf
c = wave speed
λ = wavelength
f = frequency - 11What is the equation linking frequency and time period?f = 1/T
