Direction: In the Following Questions, A Statement of Assertion (A) Is Followed by A Statement of Reason (R). Mark The Correct Choice As:
Assertion : Sunlight reaches us without dispersion in the form of white light and not as its components.
Reason : Dispersion takes place due to variation of refractive index for different wavelength but in vacuum the speed of light is independent of wavelength and hence vacuum is a non-dispersive medium.
  • 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.
  • e)
    Both Assertion and Reason are false.
Correct answer is option 'A'. Can you explain this answer?

Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A). In vacuum speed of light is independent of wavelength, Hence, no dispersion takes places in vacuum. Thus, vacuum is a non-dispersive medium in which all colours travel with the same speed.

Explanation:
Assertion (A) states that sunlight reaches us without dispersion in the form of white light and not as its components.

Reason (R) explains that dispersion occurs due to the variation of refractive index for different wavelengths. However, in vacuum, the speed of light is independent of wavelength, making vacuum a non-dispersive medium.

Analysis:
- Both Assertion (A) and Reason (R) are true as sunlight does reach us in the form of white light without dispersion and the reason for this is the non-dispersive nature of vacuum.
- Reason (R) is the correct explanation of Assertion (A) as it provides a valid scientific explanation for why sunlight is not dispersed when it reaches us.
Therefore, the correct choice is option 'A' where both Assertion (A) and Reason (R) are true, and Reason (R) is the correct explanation of Assertion (A).
