Question

(iv)Will the Focal length of concave mirror be equal to focal length of convex mirror? Give reason to your comment.​

Answer 1

Answer:

Answer. Answer: No, becz the focal length of convex will be positive and concave will be negative. So it will never be equal

Answer 2

No, the focal length of concave mirror will be not equal to the focal length of convex mirror.

• The focal length of any concave mirror is always negative.
• On the other hand, the focal length of a convex mirror is always positive.
• So, even if two convex and concave mirror have focal lengths of same numeric value, their signs will be different and the allover magnitude will be different.
• That's why, the focal length of a concave mirror and a convex mirror will never be the same.
