For a given lens in a telescope, what are the two letters corresponding to the light that gives the worst and best resolutions, respectively? (E.g., if you think that C gives the worst and A the best resolution, answer CA.)

Question

A. Green
B. Red
C. Yellow
D. Violet
E. Blue
F. Orange

Answer 1

Well, the highest frequency or shortest wavelength would give the best resolution. The highest frequency is violet.

At the long wavelength, low frequency end of the visible spectrum you have red.
