Critical angle of light passing from glass to air is minimum for wavelength of
- A red colour
- B yellow colour
- C green colour
- D blue colour
Answer & Solution
Correct Answer
(D) blue colour
Step-by-step Solution
Detailed explanation
\(\sin \mathrm{i}_{\mathrm{c}}=\frac{1}{\mathrm{n}}\) therefore \(\mathrm{i}_{\mathrm{c}}\) will be minimum when n is maximum which in this case is for blue light.
