[AIIMS 2003]
Options:
A) Polarised
B) Of longer wavelength
C) Of shorter wavelength
D) Of high intensity
Show Answer
Answer:
Correct Answer: C
Solution:
When a beam of light is used to determine the position of an object, the maximum accuracy is achieved if the light is of shorter wavelength, because $ \text{Accuracy }\propto \frac{\text{1}}{\text{Wavelength}} $
