Question
Red colored light bends ____ when passed through a prism, as compared to other colors.
- The most
- The least
- Moderately
- Does not bend
Hint:
the light rays with longer wavelengths bend less than ones with shorter wavelength
The correct answer is: The least
- On dispersion, the light rays with longer wavelengths bend less than ones with shorter wavelength. Since red has the longest wavelength, it bends the least.
