WebWhen a concave mirror is placed facing the sun, the sun's rays converge to a point 10 cm from the mirror. Now if you place a 2 cm long candle flame 20 cm awa... WebOct 20, 2024 · The rays from sun coming from infinity are parallel to principal axis after reflection they converge at a point, known as focus. Therefore, focal length (F) of concave mirror is 15 cm. And we know that same size, real and inverted image is formed by concave mirror when object is placed at centre of curvature = 2×Focal length (F).
