Wave Motion Flashcards
What is wave motion?
It is the transfer of energy by propagation of oscillations without the net movement of the medium.
What is a wavefront?
It is a surface over which a wave is at the same phase of oscillation at all points.
What is displacement of a wave?
It is the distance and direction of the medium’s element from its equilibrium position.
What is the amplitude of a wave?
It is the maximum magnitude of the displacement.
What is the period of a wave?
It is the time taken for the medium to complete one oscillation cycle.
What is frequency of a wave?
It is the number of complete oscillations per unit time made by a point of the wave.
What is wavelength?
If is the distance between two consecutive points in the wave that are at the same phase of oscillation.
What is speed of a wave?
It is the distance travelled by any pet if a waveform per unit time.
What is the phase difference between two waves or between two points in a wave?
It is the difference in the phase of their oscillation cycle expressed in terms of an angle.
Distance/wavelength x 2π
What does it mean when two waves are coherent?
There is constant phase difference between them which implies they have the same frequency.
What is the difference between two coherent waves at a particular time?
If is the distance between the points of the waves that are in the same phase out of the wavelength x2π
When the phase difference is 0 or an integer multiple of 2π, they are _____.
In phase.
What is the difference between propagation and oscillation?
Propagation is wave motion whole oscillation refers to oscillation of the medium.
What is speed of wave?(not medium!) How is it derived?
v=fλ
v= distance/time = λ/T = fλ
What is the difference between progressive waves and stationary waves?
Progressive waves transfer energy as a result of oscillation while stationary waves …..
