Correct Answer: Option 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
\(\frac{\text{image distance}}{\text{object distance}}\) = \(\frac{\text{image height}}{\text{object height}}\)
\(\frac{30}{15}\) = \(\frac{\text{image height}}{1}\)
image height = 2cm
