a) Use your model of light to predict what will happen to the image on the wall if you move the cardboard with the pin-hole (i) closer to the candle, (ii) further from the candle. Draw ray diagrams to explain your prediction. b) Use your model of light to predict what you will see on the wall if you punch a second hole in the cardboard some distance below the first hole. Support your reasoning with a ray diagram.

A candle (ho = 0.33 m) is placed to the left of a diverging lens (f = -0.063 m). The candle is do = 0.48 m to the left of the lens. You must use a ruler and draw the focal lengths and do distances to the stated scale below. Make 3 rays for each diagram. Use and scale the focal length and object position from the problem. Do not assume di from your work but rather see if the...

One way to roughly measure the focal distance of an unknown converging lens is to use it to focus a far-away object. for example, you can focus an image of the overhead light fixture onto the floor. then the distance from the lens to the floor is approximately the focal length. a. draw a ray diagram for this situation and discuss why it is a reasonable way to approximate the focal length.    b. Do you expect this method to...

Use the AS/AD model to predict how each of the following shocks would likely affect real aggregate income (Y), the overall level of real interest rates (r), and the price of goods and services (P) in the long run, all else equal. In each case, be sure to make a long run prediction (up, down, or no change) for all three variables, and illustrate your predictions with an IS/LM diagram and a supply/demand diagram for the goods market. a.Government purchases...

The U.S. Automobile Manufacturers Association needs to predict what will happen to price and output of U.S. manufactured automobiles under the conditions stated below. Consider that you have been hired to study the market and provide predictions on how the events specified will affect the market (equilibrium) price and quantity of automobiles traded. What are your predictions? Discuss and illustrate each answer with supply and demand diagram (sketch). Assume that the market for automobiles is perfectly competitive (price and output...

3. Use the classical model of a closed economy and the quantity theory of money to predict how each of the following shocks would affect real aggregate income (Y), the real interest rate (r), and the price of goods and services (P) in a closed economy in the long run, all else equal. For each shock, be sure to clearly state a prediction for all three variables (up, down, or no change) and illustrate your predictions with supply/demand diagrams for...

Part 2: Image Location 1. Place the mirror in the mirror support. Adjust the mirror support so it is located on the edge of the mirror. 2. Set the mirror in the center of a sheet of paper and place one bolt on its head directly in front of the mirror (Figure 6). Mark the locations of the mirror and bolt on the paper. Figure 6: Step 2 reference. The Blue line represents the mirror and the black dot represents...

(10%) Problem 10: A doctor examines a mole with a 15-cm focal length magnifying glass held 13 cm from the mole. Randomized Variables: do = 13 cm. (a) What is the image distance from this configuration in meters? (b) What is its magnification? (c) How big is the image of a 5.00 mm diameter mole in millimeters? You must use a ruler and draw the focal lengths and do distances to the stated scale below. Make 3 rays for each...

A. The human eye 1. Whenever a normal eye forms an image, the image distance will always equal the distance from the cornea and eye lens to the retina (~25 mm), regardless of how far away the object is located. Explain why the image distance cannot change. 2. If the image distance must change, then what intrinsic property of the eye lens must change in order for the eye to focus on objects at different distances? Hint: read the Introduction....

Problem As the resident physics expert, you’ve been called in to take care of some hornets that have been terrorizing your dorm. You find their nest is located high up in a tree. Your flamethrower is on backorder, so you’ll have to find another way to burn them out. In the deep recesses of the physics and astronomy basement, you find a very large concave spherical mirror from an old telescope. The mirror is 2 m across with an unknown...
