Question

Transcribed Image Text:Read the lab and refer to your textbook as needed to answer the following questions before coming to lab.
A simple glass convex lens can be used as a magnifying glass, or as something called a "burning glass' or
"burning lens." When used as a burning glass, sunlight is directed through the lens and focused on the object
being heated. To do this most effectively, the lens must be at a special distance from the object being heated.
Figure 1: A lens focusing sunlight on a leaf.
1. If we want to ignite a dead leaf with a burning glass, and assume the sun is an infinite distance away,
how far above the leaf should the burning glass be held to focus the rays from the sun and ignite it?
Explain why.

- Use the information from the lecture on the rules for ray tracing to complete the ray tracing for the different situations below. This part is graded on completeness so just try it out even if you feel it is wrong. Notice it is important to not get confused between the rules for lenses and mirrors. 1. Consider a concave mirror. An object is placed at various object distances from the mirror. For each case, use ray tracing to determine the following characteristics of the image: * is it real or virtual? n is it upright or inverted? n is it smaller or bigger than the object (or the same size)? n where is the image located? (approximate location – does not have to be exact) Assume a concave mirror with a focal length of f=5cm. Make sure to use a ruler and follow the ray-tracing rules. Draw a diagram for each of the following cases: (a) object is at f/2 (b) object is at f (c) object is at 3f/2 (halfway between center of curvature and focal length) (d) object is at 2f (exactly at center of…arrow_forwardWhat is the focal length of a makeup mirror that produces a magnification of 1.5 when a person's face is 12.2 cm away? Think & Prepare 1. What kind of mirror causes magnification? 2. What kind of image is it? 3. What signs will the different quantities have? (a) Set-up the table for some known quantities. i) Make sure to use the correct sign for the image distances, object distances, and the focal lengths. ii) Make sure to use the correct sign for the image and object heights. Inverted object and image heights are negative. iii) Do NOT do any calculations for this section. d₁ = M= (b) What is the focal length? f= cm cmarrow_forwardPlease type the answer instead of hand writting thanksarrow_forward
