Assertion Energy of characteristic X-rays in more than the energy of continuous X-rays
Reason Charactersitic X-rays are produced due to transition of electrons from higher energy states to lower energy states.

Options

A. If both Assertion and Reason ar 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 by Reason is false.
D. If Assertion is false but Reason is true.

Answer

To solve the question regarding the assertion and reason about characteristic X-rays and continuous X-rays, we will break down the concepts step by step.

### Step 1: Understanding X-ray Production
- **Characteristic X-rays** are produced when electrons transition from higher energy levels to lower energy levels within an atom. This transition releases energy in the form of electromagnetic radiation, which we observe as X-rays.
- **Continuous X-rays**, on the other hand, are produced when high-energy electrons are decelerated upon hitting a target material. This deceleration leads to the emission of X-rays, but these X-rays have a range of energies, typically lower than those of characteristic X-rays.

**Hint:** Recall the difference in the mechanism of production for both types of X-rays.

### Step 2: Energy Comparison
- The energy of characteristic X-rays is determined by the difference in energy levels of the electrons transitioning between specific orbits. This energy can be quite high, depending on the atomic structure of the material.
- Continuous X-rays result from the kinetic energy of the accelerated electrons being converted into electromagnetic radiation. The energy of these X-rays is generally lower than that of characteristic X-rays because it is spread over a range of energies.

**Hint:** Think about how energy levels in atoms relate to the energy of emitted radiation.

### Step 3: Analyzing the Assertion and Reason
- The assertion states that the energy of characteristic X-rays is greater than that of continuous X-rays. This is **true** based on our understanding of how each type of X-ray is produced and their respective energy levels.
- The reason provided states that characteristic X-rays are produced due to transitions of electrons from higher energy states to lower energy states. This is also **true** as it accurately describes the mechanism behind the production of characteristic X-rays.

**Hint:** Verify if the reason logically supports the assertion.

### Step 4: Conclusion
- Since both the assertion and the reason are true, and the reason explains the assertion, we conclude that the assertion is correct, and the reason supports it.

**Final Answer:** Both the assertion and the reason are true, and the reason correctly explains the assertion.
