When 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 candles flame 20 cm away on
the principal axis of the mirror, where would you place a screen to obtain the image
of the candle? What would see the size of the image? Draw a ray diagram to justify
your answer.

According to question,
Focus is located 10cm away from mirror
So f = -10cm
Given,
Height of candle (h) = 2cm
Distance of candle from pole(u) = -20cm
According to mirror formula,
So v = -20 cm
Now magnification = -v/u
So Magnification = 20/-20 = -1
So images it real, inverted, same size and formed at centre of curvation.
Screen should be placed at 20 cm away from mirror.
