Light is propagating is a direction directly away from you, with an electric field that appears to be rotating in its orientation in the counterclockwise direction. The polarization state of such a wave is:
Randomly polarized.
Plane polarized.
Left-circularly polarized.
Right-circularly polarized.
A birefringent material is best described as:
Having two different transmission axes.
Having atoms with two different resonant frequecies.
Circularly polarizing natural light.
Having two different indices of refraction.
In a Young's Double Slit interference pattern, the fourth maximum has an irradiance that is roughly:
As bright as the central maximum.
Half as bright as the central maximum.
8% as bring as the central maximum.
0.08% as bright as the central maximum.
Which of the following is true for all lenses:
All magnified images are inverted.
All virtual images are inverted.
All real images are inverted.
All diminished images are inverted.
The radius of curvature of a convex mirror of focal length -8 centimeters is:
-4 centimeters.
16 centimeters.
4 centimeters.
-16 centimeters.
Virtual images are so called because:
Light rays that form the image only appear to come from the position where the image is.
The image is too small to be seen with the naked eye.
The image can only be projected onto a screen.
The image is located behind the lens or mirror.
The spectrum observed when white light is shone through a prism is best explained by:
Diffraction
Dichroism
Distortion
Dispersion
The irradiance of a light ray is proportional to:
The frequency of the light ray.
The frequency of the light ray squared.
The amplitude of the electric field of the light ray.
The amplitude of the electric field of the light ray squared.
One reason why the sky appears blue is because:
Much more red light than blue light is absorbed by air atoms.
Red light is reflected by the atmosphere.
Blue light is scattered to a greater extent than red light.
Higher energy light waves have more penetration through the atmosphere.
Which of the following is true: I) A reflected beam always has the same irradiance as the incident beam; II) a reflected beam lies in the same plane as the incident beam; III) a reflected beam always makes an angle θ = sin-1(n t/n i) with the normal to the interface.
I only.
I and II.
II and III.
II only.
