The color of light which deviates least in a prism is:
Correct answer: A. Red
- A. Red
- B. Violet
- C. Blue
- D. Green
Explanation
Red light has the longest wavelength and lowest refractive index, so it bends the least when passing through a prism.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
