Superposition and Reflection

Reflection is...

• The frequency an object vibrates at when disturbed by an outside force.

• When an object is forced to vibrate at a specific frequency by an incident wave.

• When waves his a surface and bounce back the way they came.

• When an object is forced to vibrate at it's natural frequency.

When a ray is reflected the angle of reflection is...

• larger than the angle of incidence.

• smaller than the angle of incidence.

• equal to the angle of incidence.

• not related to the angle of incidence.

When two waves meet in space, the resultant wave will have an amplitude of...

• twice the amplitudes of the original waves.

• the sum of the amplitudes of the original waves.

• an amplitude of zero.

When two waves meet in space, if the resultant wave has a greater amplitude, they have undergone...

• constructive superposition

• destructive superposition

• transverse superposition

• longitudinal superposition

Path difference is...

• The difference in number of wavelengths from a point to two different wave sources.

• A vector sum of two different waves meeting in space.

• A point of maximum displacement in an interference pattern.

• A point of minumum displacement in an interference pattern.
