Waves Flashcards
1
Q
What are the two types of waves?
A
Transverse and Longitudinal
2
Q
What angle do the particals vibrate to the medium in transverse and longitudinal waves?
A
Transverse- Right angle to the direction as the wave energy transfer.
Longitudinal- Same direction as the wave energy transfer
3
Q
What is the definition of frequency?
A
Number of waves to pass a point in one second.
4
Q
What is the range of human hearing ?
A
20-20,000 Hz. Anything above 20kHz is Ultrasound.
5
Q
State the definition for the period of a wave and the formula used to calculate it.
A
The period of a wave is the time it takes for one wave to pass a point.
T=1/f
