Question

The image produced by an object is –10. 0 cm from a concave mirror that has a focal length of 5. 0 cm. The distance of the object from the mirror, rounded to the nearest whole centimeter, is cm.

Answer 1

The distance of the object from the mirror is 3cm.

To calculate the distance of the object from the mirror, we make use of the mirror formula

Mirror formula

• 1/f = (1/u)+(1/v)............ Equation 1

Where:

• f = Focal length of the mirror
• v = image distance
• u = object distance.

Using the real is positive convention,

Given:

• f = 5 cm
• v = -10 cm

Substitute these values into equation 1 and solve for u

• 1/5 = (-1/10)+(1/u)
• 1/5+(1/10) = 1/u
• 1/u = (2+1)/10
• 1/u = 3/10
• u = 10/3
• u = 3.33
• u = 3 cm

Hence, The distance of the object from the mirror is 3cm.
