Question

the radius of curvature of a convex mirror used as a rear view mirror in a moving car is 2.0 m. a truck is Coming from behind it at a distance of 3.5 M. calculate position and size of the image relative to the size of the truck what will be the nature of the image?

Answer 1

Answer:

Explanation:

f = r÷2 = 2m ÷ 2 = 1 m

u = -3.5 m

Using mirror formula,

1 ÷ -3.5 m + 1 ÷ v = 1 ÷ 1 m

1 ÷ v = 1 m + 1 ÷ 3.5 m

1 ÷ v = (3.5 + 1) m ÷ 3.5

1 ÷ v = 4.5 m ÷ 3.5

1 ÷ v = 9 ÷ 7 m

v = 7 ÷ 9 m

v = 0.78 m

Image will be virtual, erect and smaller than object

Answer 2

Answer:

f = r÷2 = 2m ÷ 2 = 1 m

u = -3.5 m

Using mirror formula,

1 ÷ -3.5 m + 1 ÷ v = 1 ÷ 1 m

1 ÷ v = 1 m + 1 ÷ 3.5 m

1 ÷ v = (3.5 + 1) m ÷ 3.5

1 ÷ v = 4.5 m ÷ 3.5

1 ÷ v = 9 ÷ 7 m

v = 7 ÷ 9 m

v = 0.78 m

Image will be virtual, erect and smaller than object
