Question

The magnification of a small object produced by a compound microscope is 200. The focal length of the eyepiece is 2 cm and the final image is formed at infinity. Find the magnification produced by the objective. 

Answer 1

Angular magnification = `m_0 xx D/f_e`

⇒ `200 = (m_0 xx 25)/2`

⇒ 400 = m₀ × 25

⇒ `m_0 = 400/25`

= 16
