The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided. ### Step-by-Step Solution: 1. **Understanding the Assertion (A)**: - The assertion states that "Skiers use air glasses." This is true because skiers often wear sunglasses or goggles to protect their eyes from bright sunlight and glare, especially when skiing on snow. **Hint**: Think about why skiers would need eye protection when skiing. 2. **Understanding the Reason (R)**: - The reason given is "Light reflected by snow is partially polarized." This is also true. When light hits a surface like snow, it can become polarized. This means that the light waves are oriented in a particular direction, which can cause glare. **Hint**: Recall how surfaces can affect the polarization of light and the concept of glare. 3. **Connecting the Assertion and Reason**: - The reason explains why the assertion is true. Since the light reflected off the snow is partially polarized, it can cause glare, which can be uncomfortable or even harmful to the eyes. Therefore, skiers use sunglasses or goggles to reduce this glare and protect their eyes from the polarized light. **Hint**: Consider how polarized light affects visibility and comfort in bright conditions. 4. **Conclusion**: - Both the assertion and the reason are correct, and the reason correctly explains the assertion. Therefore, the correct answer is that both the assertion and reason are true, and the reason supports the assertion. ### Final Answer: Both the assertion (A) and the reason (R) are true, and the reason correctly explains the assertion.
