chapt 9 (GWP) Flashcards
1
Q
describe what is meant by wave motion? (1)
A
a disturbance that propagates through space, transferring energy but not matter.
2
Q
what is wave speed? (1)
A
distance travelled by the wave per unit time.
3
Q
what is frequency? (1)
A
Number of oscillations each point on the waves completes per second.
4
Q
what is period? (1)
A
time taken by each point on the wave to complete one oscillation.
5
Q
what is wavefront? (1)
A
an imaginary line connecting all particles in the wave at the same phase
6
Q
formula for GWP? (2)
A
v=f X wavelength
period = 1/f
7
Q
what is a transverse wave? (1) what is a longitudinal wave? (1)
A
transverse waves has direction of vibration perpendicular to direction of wave travel.
longitudinal waves has direction of vibration parallel to direction of wave travel.
