Question

what is the formula of sperical mirror?​

Answer 1

Answer:

However, as discussed above, in the small-angle approximation, the focal length of a spherical mirror is one-half the radius of curvature of the mirror, or f=R/2. Inserting this into Equation 2.3. 11 gives the mirror equation: 1do+1di=1f⏟mirror equation.Nov 5, 2020
