C

If Assertion is true, but the Reason is false.

D

If Assertion is false but the Reason is true.

The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided. ### Step 1: Analyze the Assertion The assertion states that "In continuous X-ray spectrum, all wavelengths can be obtained." - In reality, the continuous X-ray spectrum produced by accelerated electrons in an X-ray tube does not cover all wavelengths. There is a minimum wavelength (λ_min) that can be produced, which corresponds to the maximum energy of the incident electrons. Therefore, the assertion is **false**. ### Step 2: Analyze the Reason The reason states that "Accelerated (or retarded) charged particles radiate energy. This is the cause of production of continuous X-rays." - This statement is true. When charged particles, such as electrons, are accelerated (or decelerated), they emit radiation due to their change in velocity. This is indeed the mechanism behind the production of continuous X-rays in an X-ray tube. ### Step 3: Conclusion Now that we have analyzed both parts: - The assertion is **false**. - The reason is **true**. Thus, the correct answer is that the assertion is false while the reason is true. ### Final Answer The correct option is: Assertion is false, Reason is true. ---
