Given below are two statements:
Statement I: When the white light passed through a prism, the red light bends lesser than yellow and violet.
Statement II: The refractive indices are different for different wavelengths in dispersive medium.
In the light of the above statements, choose the correct answer from the options given below:

Asked in JEE Main 5th April 2nd Shift 2024 · Dispersion and scattering

• (1) Both Statement I and Statement II are true.
• (2) Both Statement I and Statement II are false.
• (3) Statement I is true but Statement II is false.
• (4) Statement I is false but Statement II is true.

Step-by-step solution

Why the other options are wrong

• (2) Forgets that dispersion itself is caused by μ depending on wavelength.
• (3) Denies Statement II, but dispersion exists only because μ varies with λ.
• (4) Reverses the order of colours: red has the smallest μ, so it bends least.
