Question

Based on the resolving power formula RP = 1.22λ / D, if the wavelength of light (λ) increases, what happens to the numerical value of the resolving power (RP)?
Options
A It increases.
Correct Answer
B It decreases.
C It remains unchanged.
D It first increases then decreases.
Correct Answer

Option A is the correct answer.

Detailed Explanation

The formula RP = 1.22λ / D shows that RP is directly proportional to λ. If λ (the wavelength) increases, the numerator gets larger, causing the overall value of RP to increase. A larger numerical value of RP indicates a poorer ability to distinguish closely spaced objects (i.e., worse resolution).

Hint

Consider the relationship between λ and RP in the formula (inverse or direct proportionality).
