Answer on Optics Question for jphysics

Question #2854
A concave mirror collects light from a distant star. How far from the mirror is the image of the star if the radius of curvature is 150 cm?
Expert's answer
As the distance from the star can be considered as infinite, the focal length is equal to R/2 = 1.50m/2 = 0.75 m, we can use the formula:
1/f = 1/d0 + 1/d1 = 1/∞ + 1/d1
-1/0.75 = 1/d1
d1 = - 0.75.
The image is at 0.75m away from the mirror.
