X-ray beam can be deflected

Options

A. magnetic field
B. electric field
C. Both (a) and (b)
D. None of these

Explanation

To solve the question "X-ray beam can be deflected," we need to analyze the properties of X-rays and how they interact with electric and magnetic fields. Here’s a step-by-step solution:

### Step 1: Understand the nature of X-rays
X-rays are a form of electromagnetic radiation. They have properties similar to other electromagnetic waves, such as visible light, radio waves, and gamma rays.

**Hint:** Remember that X-rays belong to the electromagnetic spectrum.

### Step 2: Recall the behavior of electromagnetic waves in fields
Electromagnetic waves, including X-rays, do not carry an electric charge. As a result, they are not influenced by electric fields or magnetic fields.

**Hint:** Consider how charged particles behave in electric and magnetic fields versus neutral electromagnetic waves.

### Step 3: Analyze the options given
The options provided are:
1. Magnetic field
2. Electric field
3. Both A and B
4. None of these

Since we established that X-rays are not deflected by either electric or magnetic fields, we can eliminate options 1, 2, and 3.

**Hint:** Cross out options based on the properties of X-rays.

### Step 4: Conclude the correct answer
The only option that remains is option 4, which states "none of these." Therefore, X-ray beams cannot be deflected by either electric or magnetic fields.

**Hint:** Always check which option aligns with the established scientific principles.

### Final Answer
The correct answer is option 4: none of these.
