A)

plate A

B)

plate B

C)	plates A and B have the same potential.

D)	the plate that is closer to the positive charge

E)	it depends on the mass of the test charge

Which of the following statements about field lines is true?

A)	Field lines are always perpendicular to the surface of the object creating the field.

B)	Field lines always point in the direction of the motion of the object creating the field.

C)	Field lines never cross.

D)	Field lines are always straight.

E)	Field lines represent a force that remains uniform along the entire length of the field line.

A series of wave fronts in a wave tank travel toward an opening in a barrier. To increase the amount of visible diffraction, one could:

A)	increase the wave's amplitude

B)	decrease the wave's frequency

C)	increase the width of the opening in the barrier

D)	decrease the distance between the source of the waves and the barrier

E)	use a shorter wavelength

When two wave sources are in-phase and the wave from one source has to travel one-half wavelength further from the wave from the other source, there will be

A)	destructive interference

B)	constructive interference

C)	alternating constructive and destructive interference

D)	simultaneous constructive nor destructive interference

E)	no interaction

Proof that light is a transverse wave lays in the fact that it:

A)	can diffract

B)	slows down and bends toward the normal when it travels through a denser medium

C)	travels through space, a vacuum

D)	can be polarized

E)	can disperse when shone through a glass prism at the right angle

You and your friend are in spaceships becoming increasingly far away from one another as you shine beams of light toward one another. The spaceships are getting further apart at a rate of 0.5 c and no one is accelerating. As a result of this motion,

A)	you will see her light reaching you at a rate of 0.75 c and she will see your light approaching her at a rate of 0.75 c

B)	you will see her light reaching you at a rate of 0.5 c and she will see your light approaching her at a rate of 0.5 c

C)	what your measure for the speed of light depends on is who is really moving and who is actually at rest, and only the person truly at rest will measure light properly

D)	the effects of time dilation and length contraction will make the speed of light impossible to measure properly for both of you (no relation between your measurements)

E)	you will both measure the speed of light coming from the other spaceship to be c

Which of the following statements about quantum theory is false?

Question 36 options:

A)	Photons do not have mass or momentum.

B)	Moving particles containing mass also have wavelengths.

C)	Light exhibits both wave and particle properties.

D)	Photons are packets of energy and have wavelengths.

E)	Some electrons are not released from metallic surfaces because the frequency of the incident light is too low.
