P12 Wave Properties Flashcards
What is the difference between mechanical waves and electromagnetic waves?
Mechanical waves cannot travel in a vacuum. Electromagnetic waves can travel in a vacuum.
What are mechanical waves?
Vibrations that travel through a medium(a substance).
What is a transverse wave?
A wave which oscillates perpendicular to the direction in which the waves transfer energy.
What is a longitudinal wave?
A wave that has oscillations parallel to direction in which wave transfers energy.
What is the amplitude of a wave?
Maximum displacement of a point on wave from undisturbed position.
What is the wavelength of a wave?
Distance from a point on wave to same point on adjacent wave.
What is the frequency of a wave?
The number of waves passing a fixed point every second.
