Question

8. A 30.0 cm concave spherical mirror is used to project an image on a screen 4.00 m away. (a) calculate the object distance from the mirror.(b) Calculate the magnification of the image. (c) is the image erect or inverted?

Answer 1

a - do di tot do= object distance = ? di= image distance f = focal length - 4m = 400cm = 30cm. +Išo do 400 do = 1/30 - 14.00 do 30 x 400 = 32.43cm -0.3243 meres. 400-30 400 m - = 12.33 32.43 b) magnification, di do is inverted because, because image Image screen (geren in question). Hence inverted. c) is formed is read Real on the image is
