Pregunta 1
Pregunta
How is sound produced?
Respuesta
-
Through the creation of electrical energy which travels though through an elastic medium
-
Through the displacement of an elastic medium
-
Through the creation of mechanical energy that breaks down an elastic medium
-
Through the displacement of a mechanical medium
Pregunta 2
Pregunta
When does a) compression and b) rarefaction occur?
Respuesta
-
a) When there is a reduction in pressure at a point in the elastic medium b) When there is an increase in pressure at a point in the elastic medium
-
a) When there is an increase in pressure at a point in the elastic medium b) When there is a decrease in pressure at a point in the elastic medium
-
a) When there is no pressure change at a point in the elastic medium b) When there is a decrease in pressure at a point in the elastic menium
-
a) When there is an increase in pressure at a point in the elastic medium b) When there is no pressure change at a point in the elastic medium
Pregunta 3
Pregunta
How is the sound transmitted across the elastic medium (to the ear)?
Respuesta
-
It's propagated along a wave of mechanical energy until it is funneled into the ear by the pinnae
-
It is propagated along a wave of neural energy until it is funneled into the ear by the pinnae
-
It is propagated along a wave of neural energy until it makes contact with the pinnae resulting in an action potential
-
It is propagated along a wave of mechanical energy until it makes contact with the pinnae resulting in an action potential
Pregunta 4
Pregunta
When can the process of sound transmission occur?
Respuesta
-
When there is carbon dioxide present to fuel the energy
-
When there is an elastic medium present such as in water or in a vacuum
-
In a vacuum only
-
When there is en elastic medium present
