Question

When an object is viewed with a light of wavelength \( 6000 \,\text{\AA} \) under a microscope its resolving power is \( 10^4 \). The resolving power of the microscope when the same object is viewed with a light of wavelength \( 4000 \,\text{\AA} \) is

• A. $10^4$
• B. $2 \times 10^4$
• C. $3\sqrt{2} \times 10^4$
• D. $3 \times 10^4$
• E. $1.5 \times 10^4$

Hint:

Resolving power $\propto \frac{1}{\lambda}$ → smaller wavelength gives sharper image.
