chapter 11: waves 🌊 Flashcards
1
Q
define transverse wave
A
oscillations of a particle is perpendicular to the direction of propagation of the wave
2
Q
define longitudinal wave
A
oscillation of particles parallel to the direction of propagation of wave
3
Q
define frequency
A
number of oscillations performed by a particle per unit time
4
Q
define wavefront
A
imaginary line joining all the points of the wave that have the same phase
5
Q
define intensity
A
rate of flow of energy per unit area perpendicular to the direction of wave
6
Q
why can’t longitudinal waves be polarised
A
direction of vibration is the same as the direction of wave propagation
