Question

1. A luminous object is 4.2m from a wall. You are to use a convave mirror to project an image of the object on the wall. With the image 2.27 the size on the object.
A. How far should the mirror be from the wall? B. What should the radius of curvature be?
2. A concave mirror has a radius of curvature of 34.2 cm.
A. What is its focal length? B. A ladybug 7.55cm tall is located 21.8cm from this mirror along the principal axis. Find the location of the image of the insect. C. Find the height of the image of the insect. D. If the mirror is immersed in water (of refraction index 1.33), what is its focal length? 1. A luminous object is 4.2m from a wall.

Explanation / Answer

1. A luminous object is 4.2m from a wall. You are to use a convave mirror to project an image of the object on the wall. With the image 2.27 the size on the object.

magnification = 2.27 =Di /Do

2.27Do = Di

Do = Di
