An object is placed infront of a concave mirror of focal lenght 30cm. Virtual image of object is obtained at a distance of 20cm from the mirror. Calculate the positon of the object?
Solution
This is a simple question with direct application of the mirror formula.
1/v + 1/u = 1/f
f = -30 cm
v = +20 cm (virtual image)
