A concave lens has a focal length of 30 cm. Find the position and magnification (m) of the image for an object placed in front of it at a distance of 30 cm. State whether the image is real or virtual ?

As we know, the lens formula is Given, f = - 30 cm u = - 30 cm Substituting the values in the formula, we get, Therefore, the image in formed 15 cm in front of the lens. ii) As we know, the formula for magnification of a lens is Given, u = - 30 cm v = - 15 cm Substituting the values in the formula, we get, Therefore, the magnification is +0.5 The image is virtual as the magnification is positive.
