Sound Propogation Flashcards
1
Q
What is sound propagation?
A
How it travels
2
Q
What is the law of reflections?
Incident ray
Reflected ray
Angles
A
The incident ray and the reflected ray make equal angles with the normal to the surface
I=r
3
Q
When does diffuse reflection occur?
Rough surface
Wave energy scattered in many different directions
A
Waves encounter a rough surface with bumps as large as the wavelength of the waves
4
Q
What is refraction?
Change of direction
Change in its speed
A
Change of direction in wave travel due to the difference in speed from one place to another
