An object 1cm high placed on the axis 15cm from a converging lens forms an image 30cm from the lens. The size of the image is

Options

A) 0.5cm

B) 1.5cm

C) 3cm

The correct answer is E.

Explanation:

\(\frac{\text{image distance}}{\text{object distance}}\) = \(\frac{\text{image height}}{\text{object height}}\)
\(\frac{30}{15}\) = \(\frac{\text{image height}}{1}\)
Image height = 2cm
