NEET Physics Reflection MCQ Question
A concave mirror forms a real, inverted image of an object placed at a distance of 30 cm from it. If the focal length of the mirror is 15 cm, what is the image distance?
15 cm
30 cm
45 cm
60 cm
Correct Answer
Detailed Explanation
Using the mirror equation 1/v + 1/u = 1/f with u = -30 cm and f = -15 cm, we find v = -30 cm, indicating the image is formed 30 cm from the mirror.
