Question 1

Two positive thin lenses are separated by a distance of 5.00 cm. The focal lengths of the lenses are F1 = 10.0 cm and F2 = 20.0 cm. Using ray tracing along with numerical methods, determine the power of the combination in 1/cm. Express your answer with three significant figures.

Question 2

What is the back focal distance of the two lens system described in question 1, in cm? Express your answer with 2 significant figures.

Question 3

What is the front focal distance of the two lens system described in question 1, in cm? Express your answer with 2 significant figures.

Question 4

What is the location of the front principle plane of the two lens system described in question 1, measured relative to the first lens, in cm?

If the front principle plane is to the left of the first lens (before the lens), enter you answer as a negative number; if it is to the right of the first lens (after the lens), enter your answer as a positive number. Express your answer with 2 significant figures.

Question 5

What is the location of the back principle plane, measured relative to the first lens again, in cm? If the back principle plane is to the left of the first lens (before the lens), enter you answer as a negative number; if it is to the right of the first lens (after the lens), enter your answer as a positive number. Express your answer with 2 significant figures.

Question 6

If an object is placed 2.0 cm to the left of the front focal point, where is the image located relative to the back focal point? Express your answer in cm. Express your answer with 2 significant figures.

Question 7

What is the magnification of the image for the situation described in question 6? Express your answer with 2 significant figures.

Question 8

What is the throw of the system described in question 6? The throw is defined as the distance between the object and the image. Express your answer in cm, with 2 significant figures

Question 9

For a myopic swimmer with a prescription of -7.0 diopters, what should the radii of curvature of the lens surfaces be if the goggles are made from a high index plastic of n = 1.6? First, what is the radius of curvature of the outer surface (furthest from the eye)? If the surface is flat, enter 'i' for an infinite radius.

Express your answer in cm and round to a single decimal place.

Question 10

For the myopic swimmer with a prescription of -7.0 diopters, what should the radii of curvature of the lens surfaces be if the goggles are made from a high index plastic of n = 1.6? First, what is the radius of curvature of the inner surface (closest to the eye)?

If the surface is flat, enter 'i' for an infinite radius.

Express your answer in cm and round to a single decimal place.
