Question
The angle of deviation is ________ for a violet light.
- The least
- The most
- Zero
- None of the above
Hint:
angle of deviation is inversely propoyional to refracrive index
The correct answer is: The most
The redfractive index for red is least and for violet it is maximum
As the wavelength of red light is more as compared to violet so red has smaller redfractive index than violet.
Also angle of deviation is inversely propotional to refracrive index so angle of deviation of violet is least
