P1.5 Waves Flashcards
1
Q
What are the features of a wave?
A
Frequency, wavelength, amplitude.
2
Q
What is frequency?
A
Number of waves that arrive every second (Hz)
3
Q
What is wavelength ?
A
Distance from one crest to the next (m)
4
Q
What is amplitude?
A
Maximum distance of a point on the wave from its rest position.
5
Q
What is a longitudinal wave?
A
Waves in which oscillations are along the line of the direction of the wave movement
6
Q
What is an example?
A
Sound waves
7
Q
What is a transverse wave?
A
Waves in which oscillations are at right angles to the direction of energy movement.
8
Q
What is an example?
A
Light wave
9
Q
Can transverse waves travel through a vacuum?
A
Yes
10
Q
Can longitudinal?
A
No
11
Q
Wave calculations
A
Speed/wavelength=frequency
Wavelength*frequency=speed
speed/frequency= wavelength
