Directions: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:
Assertion (A): A white light on passing through prism splits into its component colours as such that the red light emerges nearest to the base of the prism.
Reason (R): Wavelength of red light is more than other component colours and hence, red light deviates least.
- a)Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
- b)Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
- c)Assertion (A) is true but reason (R) is false.
- d)Assertion (A) is false but reason (R) is true.
Correct answer is option 'D'. Can you explain this answer?

Directions: In the following questions, a statement of assertion (A) ...
Dispersion takes place because the refractive index of medium for different wavelengths (colours) is different. The refractive index is inversely proportional to l Since lred is more than other colours wavelength. So, deviation is least for red and it appears farthest from the base of the prism.

Directions: In the following questions, a statement of assertion (A) ...
Assertion: A white light on passing through prism splits into its component colours such that the red light emerges nearest to the base of the prism.
Reason: The wavelength of red light is more than other component colours and hence, red light deviates least.
Explanation:
- When a beam of white light passes through a prism, it undergoes dispersion, which means it splits into its component colors. This happens because different colors of light have different wavelengths and hence different refractive indices.
- The refractive index of a medium depends on the wavelength of light. The shorter the wavelength, the higher the refractive index.
- According to Snell's law, when light passes from one medium to another, it bends or deviates from its original path. The amount of deviation depends on the refractive index of the medium.
- In the case of a prism, the angle of deviation is different for different colors of light because they have different wavelengths and refractive indices.
- Red light has the longest wavelength among the visible colors, and hence it has the least refractive index. This means that red light deviates the least when passing through a prism.
- As a result, when white light passes through a prism, the red light is the least deviated and emerges nearest to the base of the prism.
- On the other hand, colors with shorter wavelengths like violet and blue have higher refractive indices and are deviated more than red light. They emerge farthest from the base of the prism.
- Therefore, the reason provided is correct. The wavelength of red light is more than other component colors, and it deviates the least in a prism, causing it to emerge nearest to the base.
Conclusion: Both the assertion and reason are true, and the reason is the correct explanation of the assertion.
Reason: The wavelength of red light is more than other component colours and hence, red light deviates least.
