Question

An object is 3.0 cm from a concave mirror, with a focal length of 1.5 cm. Calculate the image distance. Remember to include your data, equation, and work when solving this problem. A concave mirror is shown with curvature positioned at 8 on a ruler that goes from 0 to 14 centimeters. The object is located at 5, and the focal point is located at 6.5.

Answer 1

The image distance is 3.0 cm

Step-by-step explanation:

Object distance: 3.0 cm Focal length: 1.5 cm Image distance: ? cm

1/f=(1/ do）+（1/di​​​​​​​)

1/1.5=(1/3.0)+(1/x)

(2/3)-(1/3)=1/x

1/3=1/x

x=3.0 cm

The image distance is 3.0 cm.
