The correct Answer is:
To analyze the assertion and reason provided in the question, we will break down the concepts step by step. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that a photocell is called an "electric eye." - A photocell is indeed often referred to as an electric eye because it detects light and can trigger electrical responses based on that detection. 2. **Understanding the Reason**: - The reason states that a photocell can "see" the things placed before it. - However, this is misleading. A photocell does not "see" in the way that humans or animals do. It detects light intensity and converts it into electrical signals, but it does not have the capability to visually perceive objects. 3. **Function of a Photocell**: - A photocell operates by converting light energy into electrical energy. It is commonly used in applications such as burglar alarms, where it detects specific light frequencies and triggers an alarm when light is detected. 4. **Conclusion**: - The assertion is true: a photocell is often called an electric eye due to its function of detecting light. - The reason is false: a photocell does not "see" objects; it only responds to light intensity. 5. **Final Evaluation**: - Since the assertion is true and the reason is false, the correct answer to the question is that the assertion is true, but the reason is false. ### Final Answer: - The assertion is true, but the reason is false. ---
To analyze the assertion and reason provided in the question, we will break down the concepts step by step. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that a photocell is called an "electric eye." - A photocell is indeed often referred to as an electric eye because it detects light and can trigger electrical responses based on that detection. ...
