An object 2 cm high is placed 5 cm away from a concave spherical mirror having radius of curvature of 20 cm. Determine the position, size, orientation and nature of the image. [10 cmbehind the mirror, 4 cm, erect, virtual]
Added by Jeff M.
Step 1
First, we need to find the focal length of the mirror. The formula for the focal length (f) of a spherical mirror is: $$ f = \frac{R}{2} $$ where R is the radius of curvature. In this case, R = 20 cm, so: $$ f = \frac{20}{2} = 10 \, \text{cm} $$ Show more…
