Assertion: Ultraviolet radiation are of higher frequency waves are dangerous to huhman beaing.
Reasion: Ultraviolet radiation are absorbed by the atmosphere

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 correct explanation of Assertion.
C. If Assertion is true but Reason is false.
D. If Assertion is false but Reason is true.

Explanation

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

### Step 1: Analyze the Assertion
The assertion states that "Ultraviolet radiation are of higher frequency waves and are dangerous to human beings."
- **Explanation**: Ultraviolet (UV) radiation does indeed have a higher frequency compared to visible light, and it is known to be harmful to humans. Prolonged exposure to UV radiation can lead to skin damage, skin cancer, and eye problems such as cataracts.

### Step 2: Analyze the Reason
The reason states that "Ultraviolet radiation are absorbed by the atmosphere."
- **Explanation**: This statement is also true. The Earth's atmosphere, particularly the ozone layer, absorbs a significant portion of UV radiation from the sun. This absorption helps protect living organisms from harmful effects of UV radiation.

### Step 3: Determine the Relationship
Now we need to determine if the reason provided is a correct explanation of the assertion.
- **Explanation**: While both the assertion and the reason are true, the reason does not explain why UV radiation is dangerous to humans. The danger comes from the radiation itself, not from its absorption by the atmosphere.

### Step 4: Conclusion
Since both the assertion and the reason are true, but the reason does not correctly explain the assertion, the correct answer is that both statements are true, but the reason is not the correct explanation of the assertion.

### Final Answer
Both the assertion and the reason are true, but the reason is not the correct explanation of the assertion. Therefore, the answer is option B.
