Q. We're standing between the focal point of a concave mirror and the mirror. What do we see?
enlarged, upright, real image
enlarged, inverted, virtual image
enlarged, upright, virtual image
shrunken, upright, virtual image
shrunken, upright, real image
Q. Young's Double Slit Experiment illustrates
the wave nature of light
the particle nature of light
the wave-particle duality of light
the refractive nature of light
the reflective nature of light
Q. Oranges look orange because
they have orange pigments
they reflect only orange light
they reflect all wavelengths of light except for orange
they absorb orange light
they taste better that way
Q. When two waves of the same wavelength meet peak to peak they
say hello
interfere destructively to form a wave with a smaller amplitude or cancel each other out
interfere constructively to form a wave with a smaller amplitude or cancel each other out
interfere destructively to form a wave with a larger amplitude
interfere constructively to form a wave with a larger amplitude
Q. Looking at a 2 m tall tree through a convex lens and creates an image 1 m tall and upside down. Where is the tree relative to the lens and its focal point?
between the focal point and the lens
between the focal point and 2F
beyond 2F
at the focal point
right at the lens
Q. We see a larger, right side up version of ourselves in a concave mirror. We look twice as tall as we really are while standing 4 m from the mirror. At what distance from the mirror is the image formed?
-8 m
8 m
4 m
16 m
-4 m
Q. Light moves from a medium with a high index of refraction to one with a low index of refraction. The light will:
be bent away from the normal
be bent towards the normal
will travel straight through the object without altering its path
will experience total internal reflection
will form a diffraction pattern
Q. We position a lens such that a tree is between the focal point F and 2F of the lens. We also measure that the tree is 5 m away from the lens and that the distance from the lens to the point at which the image is formed is also 5 m. What is the focal length of this lens?
5 m
1 m
2.5 m
0 m
-2.5 m
Q. The magnification factor of an upside down image is
either positive or negative
depends on whether the image is generated by reflection or refraction
always positive
zero
always negative
Q. A person looking in a concave mirror standing between the center of curvature and the focus is 1.6 m tall and the image height is 16 m. What is the magnification factor?

0.1
