The correct Answer is:
To solve the question regarding the speed of emitted X-rays in an X-ray tube where electrons are accelerated through a potential difference of 15,000 volts, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Nature of X-rays**: X-rays are a form of electromagnetic radiation. The speed of electromagnetic waves, including X-rays, is constant in a vacuum. 2. **Identify the Speed of Light**: The speed of light in a vacuum is approximately \( c = 3 \times 10^8 \, \text{m/s} \). 3. **Recognize Independence from Potential Difference**: The speed of X-rays does not depend on the potential difference through which the electrons are accelerated. Regardless of the voltage applied (in this case, 15,000 volts), the speed of X-rays remains the same. 4. **Conclude the Speed of Emitted X-rays**: Therefore, the speed of the emitted X-rays inside the tube is \( c = 3 \times 10^8 \, \text{m/s} \). ### Final Answer: The speed of the emitted X-ray inside the tube is \( 3 \times 10^8 \, \text{m/s} \). ---
