Document Summary

Chapter 3 (2nd half): spherical lenses and aberrations. If the lens is immersed in a liquid whose index of refraction is greater than itself the effect of the lens is reversed. It can be corrected by adding a lens with a different index of refraction: spherical aberration: there are multiple areas of focus where the rays intersect. Chapter 5: the human eye and vision: monocular vs. binocular, monocular vision is when only one eye views an image. Since only one eye is viewing the image there is no depth perception: binocular vision is when both eyes view an image. Since both eyes view the image there is depth perception. Iris - diaphragm of the camera: pupil - aperture, eyelids - not analogous to a shutter, but acts like a lens cover, keeping dirt out, retina - acts as film, and contains millions of cells, rods and cones. Chapter 6. 1 and 6. 2: the eye"s point of view.

Draw the three "special rays" from the tip of the arrow. Use a straightedge.
1. A ray parallel to the axis (Ray 1) refracts through the far focal point.
2. A ray that enters the lens along a line through the near focal point (Ray 2) emerges parallel to the axis.
3. A ray through the center of the lens (Ray 3) does not bend.
Extend the rays until they converge. This is the image point. Draw the rest of the image in the image plane. If the base of the object is on the axis, then the base of the image will also be on the axis.

An object O is placed at the location shown in front of a concavespherical mirror. Use ray tracing to determine the location andsize of the reflected image. As you work, keep in mind thefollowing properties of principal rays:

A ray parallel to the axis, after reflection, passes through thefocal point F of a concave mirror or appears to come from the(virtual) focal point of a convex mirror.
A ray through (or proceeding toward) the focal point F is reflectedparallel to the axis.
A ray along the radius through or away from the center of curvatureC intersects the surface normally and is reflected back along itsoriginal path.
A ray to the vertex V is reflected, forming equal angles with theoptic axis.

25) A negative magnification for a mirror means that

A) the image is upright, and the mirror could be either concave or convex.

B) the image is inverted, and the mirror is concave.

C) the image is inverted, and the mirror could be either concave or convex.

D) the image is upright, and the mirror is convex

E) the image is inverted and the mirror is convex.

26) An object is placed in front of a thin lens, Which statements are correct in describing the image formed by the lens? (There could be more than one correct choice.)

A) If the lens is convex, the image must be real.

B) If the image is real, then it is also inverted.

C) If the image is real, then it is also upright.

D) If the lens is convex, the image will never be virtual.

E) If the lens is concave, the image must be virtual.

27) When a beam of light, originally travelling in air, enters a piece of glass having an index of refraction of 3/2, its frequency

A) is unaffected

B) is reduced to 2/3 its original value.

C) increased by a factor of 3/2.

28) The index of refraction of a type of glass is 1.50, and the index of refraction of water is 1.33. If the light enters water from the glass, the angle of refraction will be

A) equal to the angle of incidence.

B) less than the angle of incidence.

C) greater than the angle of incidence.

29) Which of the following terms describe lenses that are thinner at the center than the edges? (there could be more than one correct choice.)

A) concave lenses

B) converging lenses

C) diverging lenses

D) convex lenses

30) You may have seen ambulances on the street with the letters of the word AMBULANCE written on the front of them, in such a way to appear correctly when viewed in your car's rear-view mirror. (See the figure.) How do the letters appear when you look directly at the ambulance (not through the mirror)?
