Question

Suppose a 1.5 cm tall object is placed 6.5 cm in front of a spherical convex mirror with focal length -2.8 cm. Draw a ray diagram that accurately shows the image. The image is {a. upright b. inverted}. The image is {a. real b. virtual}. The image position is a. -0.2030 cm b. -1.409 cm c. -1.932 cm d. -1.206 cm e. 1.217 cm e. 1.217 f. 1.891 cm The magnification is a. 0.1509 b. 0.2072 c. -0.1912 d. 0.3196 e. -0.3183 f. 0.2973 The height of the image is a. 0.3205 cm b. 0.4459 cm c. -0.4918 cm d. -0.2670 cm e. -0.2649 cm f. 0.01260 cm

Explanation / Answer

y = 1.5 cm

u = 6.5 cm

f = -2.8 cm

1/f = 1/u+1/v

v = uf/u-f = -1.95 cm

up right and virtual

magnification m = -v/u = 0.3

m = y'/y

y' = 0.45 cm
