Question

HRW6 35-10P Fill in Table 35-3, each row of which refers to a different combination of an object and either a plane mirror, a spherical convex mirror, or a spherical concave mirror. Distances are in centimeters. If a number lacks a sign, find the sign. To help yourself, sketch each combination and draw in enough rays to locate the object and its image. Table 35-3 Mirrors REAL IMAGE? 6 INVERTED IMAGE? TYPE a) concave +10.0 20.0 +10.0 +1.00 40 +20.0 +30.0 +60.0 0.500 es 40.0 10.0 +0.100 20.0 (g) convex 40.0 4.00 +24.0 0.500

Please answer the blanks

Answer 1

a) 1/i = 1/f - 1/p = 1/20 - 1/10

i = - 20 cm

m = -i / p = - ( - 20) / p = 20 / 10 = 2

b) m = -i/p

i = m*p = 10*1 = - 10

i = -10 cm

____________________________________________________________________________________________

c) 1/i = 1/20 - 1/30

i = 60 cm

m = - 60 / 30 =

m = -2

d) r = 40 cm , so f = 40/2 = 20 cm

1/i = 1/20 - 1/60

i = 30 cm

m = -30 / 60

m = -0.5

___________________________________________________________________________________________

e) 1/p = 1/f - 1/i

1/p = -1/20 - (-1/10)

p = 20 cm

m = - (-10) / 20

m = 0.5
