CBSE · Class 10 · Science · Light – Reflection and RefractionState the conditions under which a concave mirror forms a virtual and erect image.
Step-by-Step Solution
A concave mirror forms a virtual and erect image only when the object is placed exceptionally close to the mirror, specifically between its pole and its principal focus. Under this specific condition, the reflected rays diverge after reflection and appear to come from a point behind the mirror when extended backward. This unique property of concave mirrors is utilized in makeup mirrors and dentist mirrors to obtain an enlarged, erect, and magnified view of small objects placed within the focal length.
