Question

A slide projector uses a thin lens with a focal length 132 mm to project a clear image on a screen located 10.5 m from the lens. Calculate the distance the slide is from the lens and the magnification obtained. 513 mm, m = -20.5 134 mm, m = -78.4 154 mm, m =-54.9 513 mm, m = 20.5 585 mm, m = -17.9 Question 14 5 pts A convex spherical mirror with a radius of curvature of 100 cm generates an upright image 29.7 cm from the mirror. What is the magnification of the image? O 1.60 o o 0.60 0.33 0.41 2.46

Answer 1

- DATE: Sol using long formula; I 1 715 + 132 x 103 10.5 te Tous 10.5 1000 132 U=0:13 4 m or U=-134mm -resign Shows in front of lens) 78.4 magnification m= SI 10.5 -134 Hence Answer is 134 mm m=-78.4 option

focal length f = B = 100 350 cm 2 2 :) U= 29.7 cm using missor formula, H: * > 이 =) f u 26.7 + 50 29.7 U= -73. 1 cm. & magnification 21 ma 는 29.7 - 73.1 ma 0,41 Sophiend
