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): Sunlight reaches us without dispersion in the form of white light and not as its components.
Reason (R): Dispersion takes place due to variation of refractive index for different wavelengths 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.
Correct answer is option 'A'. Can you explain this answer?

For Assertion
View all questions of this test
• Dispersion only occurs after the sunlight enters the atmosphere at a minor rate.
• So sunlight reaches us without dispersion in the form of white light and not as its components.
• Therefore, the assertion is true.
Dispersion of White Light
For reasoning
• This happens because before entering the atmosphere, sunlight passes through vacuum
• In vacuum, light does not disperse
• In vacuum, all colours travel with the same speed.
Thus, Reasoning is also true.
Thus,
• Assertion is True
• Reasoning is True
• And the reason is the correct explanation for the assertion.
Hence, Correct Option is A

Assertion and Reasoning
Assertion (A): Sunlight reaches us without dispersion in the form of white light and not as its components.
Reason (R): Dispersion takes place due to variation of refractive index for different wavelengths but in vacuum the speed of light is independent of wavelength and hence vacuum is a non-dispersive medium.
Explanation
• Assertion (A) is true because when sunlight enters the Earth's atmosphere, it appears white to us. This is because the Earth's atmosphere acts as a non-dispersive medium and does not separate the different colors of sunlight.
• Reason (R) is also true because dispersion occurs when light passes through a medium with varying refractive indices for different wavelengths. This causes the different colors of light to bend at different angles and separate. However, in a vacuum, the speed of light is constant and does not depend on the wavelength. Therefore, a vacuum is a non-dispersive medium.
• Reason (R) provides the correct explanation for assertion (A) because it explains why sunlight appears as white light when it enters the Earth's atmosphere. The non-dispersive nature of the Earth's atmosphere, combined with the non-dispersive nature of vacuum, results in the white light reaching us without separation into its component colors.
Therefore, the correct answer is option (A) - Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
Assertion (A): Sunlight reaches us without dispersion in the form of white light and not as its components.
Reason (R): Dispersion takes place due to variation of refractive index for different wavelengths but in vacuum the speed of light is independent of wavelength and hence vacuum is a non-dispersive medium.

Directions: In the following questions, a statement of assertion (A) ...
In vacuum speed of light is independent of wavelength. Hence, no dispersion takes place in vacuum. Thus, vacuum is a non dispersive medium in which all colours travel with the same speed.
