Identify the incorrect statements with reference to dispersion of white light.

(A) Red light gets most deviated while passing through the prism.
(B) Thick lenses show chromatic aberrations due to dispersion.
(C) Refractive index of medium for different colours is different.
(D) Red light travels faster than violet light in the prism.
(E) While light, once dispersed, cannot be recombined.

Choose the correct answer from the options given below:

(A) and (E) only

The correct answer is Option (3) → (A) and (E) only

(A) Red light gets most deviated — Incorrect. In dispersion through a prism, violet light deviates the most and red the least.

(B) Thick lenses show chromatic aberrations due to dispersion — Correct. Dispersion causes different colours to focus at different points.

(C) Refractive index of medium for different colours is different — Correct. This difference is the very reason dispersion occurs.

(D) Red light travels faster than violet light in the prism — Correct. Since red has a lower refractive index, its speed in the medium is higher than violet.

(E) White light, once dispersed, cannot be recombined — Incorrect. Dispersed light can be recombined using another prism or lens.
