Assertion: Incoming light reflected by earth is partially polarized.
Reason: Atmospheric particle polarize the light.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reason are true but reason is not the correct explanation of assertion.
C. If assertion is true but reason is false.
D. If both assertion and reason are false.

Answer

To solve the question, we need to analyze the assertion and the reason provided.

### Step 1: Understand the Assertion
The assertion states that "Incoming light reflected by Earth is partially polarized." This means that when sunlight (or any incoming light) hits the Earth's surface and reflects back, some of that light becomes polarized.

### Step 2: Understand the Reason
The reason given is that "Atmospheric particles polarize the light." This suggests that the particles in the Earth's atmosphere interact with the incoming light, causing it to become polarized.

### Step 3: Analyze the Interaction
When light enters the Earth's atmosphere, it encounters various particles (like dust, water droplets, etc.). These particles can scatter the light. The scattering process can lead to polarization, especially when the light is reflected off surfaces or when it interacts with particles at certain angles.

### Step 4: Conclusion
Since the assertion states that the light reflected by Earth is partially polarized, and the reason explains that atmospheric particles are responsible for this polarization, we can conclude that both the assertion and the reason are true. Moreover, the reason correctly explains the assertion.

### Final Answer
Both the assertion and the reason are true, and the reason is the correct explanation for the assertion.
