Waves Flashcards
What is meant by transverse wave?
It is a wave in which the displacement of particles is perpendicular to the direction of wave motion.
Describe features of resultant wave set up by two waves travelling in opposite directions.
Resultant wave is a stationary wave with twice the amplitude of each individual wave.
The waveform does not advance and there is no transfer of energy.
The particles vibrate about their equilibrium positions with maximum amplitude at antinodes and zero at nodes.
All particles between two nodes are in phase, and in anti-phase on opposite sides of nodes.
What is wavelength?
Distance travelled by the wave in one period.
What is meant by progressive wave?
It is a wave in which it travels from one point to another with a transfer of energy along its direction of travel.
(Transverse waves and longitudinal waves are part of progressive waves)
What is speed in terms of movement of waves?
It is the distance the wave moves per unit time.
What is a longitudinal wave?
It is a wave in which the displacement of particles is parallel to the direction of wave motion.
