Answer :
Final answer:
The power of a concave mirror with a radius of curvature of 20 cm is +5.00 D.
Therefore, the correct answer is d. +5.00 D.
Explanation:
The power of a concave mirror can be determined using the formula:
Power of concave mirror = 2/R
where R is the radius of curvature of the mirror.
In this case, the radius of curvature is 20 cm, so the power of the concave mirror is:
Power = 2/20 = 0.10 D
Therefore, the correct answer is d. +5.00 D.
