1
Q
Describe the different types of waves and their features
A
Longitudinal wave - the oscillation is parallel
Transverse wave - the oscillation is 90 degrees to the direction of the wave
Reflection wave - the wave bounces off a barrier
Incident wave - the wave goes into a barrier
2
Q
What happens when waves superpose?
A
When waves superpose they either add up or cancel out
3
Q
How is sound produced and how does it travel?
A
Sound is produced by vibrations and travels by bounces off molecules
4
Q
Why is the speed of sound different in different materials
A
Sound is faster in different materials because their are more molecules per cm3
5
Q
The speed of light vs the speed of sound
A
The speed of sound = 300m/s
The speed of light = 300 million m/s
