Question

An object is placed 5.00 cm beyond the focal point of a convex lens whose focal length is 10.0 cm. Calculate the image distance from the lens. Si = _____ cm

6.0
30.0
0.033
0.17

Answer 1

Si = 30.0 cm

Step-by-step explanation:

Answer 2

We are given:
object distance o = 5.00 cm + 10.0 cm = 15.0 cm
focal length f = 10.0 cm
image distance i = ?

Using the Thin Lens Equation:
1/f = 1/o + 1/i
we substitute the values which leaves us with:
1/i = 1/10.0 - 1/15.0
1/i = 1/30.0

i = 30.0 cm
