Question

At what position should be the candle kept by Sunidhi to obtain a virtual image of the candle using concave mirror?

• A. Between infinity and the centre of curvature
• B. Between the focus and the centre of curvature
• C. Between the pole and the focus
• D. Between the infinity and focus

Answer 1

The correct option is C Between the pole and the focus

The ray diagram of an object kept in between the pole and the focus is shown above.

When an object is kept in between the pole and focus of the concave mirror, then the virtual, enlarged and erect image is formed behind the mirror.

At rest of all the positions of the object, the concave mirror forms a real image.
