Question

In a spectrophotometer, the monochromator must be able to resolve two wavelengths 599.0nm and 600.1nm. The required resolution is

• A. 100
• B. 500
• C. 1000
• D. 3000

Hint:

The theoretical resolving power $R = \frac{\lambda}{\Delta\lambda}$ gives the absolute minimum limit.
Practical systems are designed with higher values (e.g., several times the theoretical limit) to ensure adequate separation under real-world slit-width conditions.

Answer 1

The Correct Option is D
