Question

What will be the expression for the angular magnification produced by the telescope?

• A. $m_{\theta }=\frac{f_e}{f_o}$
• B. $m_{\theta }=\frac{f_o}{f_e}$
• C. $m_{\theta }=\frac{1+f_e}{f_o}$
• D. $m_{\theta }=\frac{1+f_o}{f_e}$

Answer 1

The correct option is B

$m_{\theta }=\frac{f_o}{f_e}$

Hey, you know the definition of angular magnification; $m_{\theta }=\frac{{\theta }_i}{{\theta }_o}$. Use this and try to derive the angular magnification for the microscope, take 2-3 minutes. Then proceed to the next video for the explanation.
