Electromagnetic wave is deflected by

Options

A. Electric field
B. Magnetic field
C. Both (1) and (2)
D. Neither electric field nor magnetic field

Answer

To solve the question "Electromagnetic wave is deflected by", we need to analyze the properties of electromagnetic waves and their interaction with electric and magnetic fields.

### Step-by-Step Solution:

1. **Understanding Electromagnetic Waves**:
- Electromagnetic (EM) waves are oscillations of electric and magnetic fields that propagate through space. They do not consist of charged particles.

2. **Effect of Electric Field on Charged Particles**:
- When a charged particle (like an electron) is placed in an electric field, it experiences a force and can be deflected. However, EM waves themselves do not contain charged particles.

3. **Effect of Magnetic Field on Charged Particles**:
- Similarly, when a charged particle moves through a magnetic field, it also experiences a force that can cause deflection. Again, EM waves do not have charged particles.

4. **Behavior of EM Waves in Fields**:
- EM waves propagate through space without being deflected by electric or magnetic fields. They can be described as oscillations in the electric and magnetic fields, but they do not change direction due to these fields.

5. **Evaluating the Options**:
- Option 1: Electric Field - Incorrect, as EM waves are not deflected by electric fields.
- Option 2: Magnetic Field - Incorrect, as EM waves are not deflected by magnetic fields.
- Option 3: Both Electric and Magnetic Fields - Incorrect, as neither field deflects EM waves.
- Option 4: Neither Electric Field nor Magnetic Field - Correct, as EM waves are not deflected by either.

6. **Conclusion**:
- The correct answer is Option 4: Neither Electric Field nor Magnetic Field.

### Final Answer:
Electromagnetic waves are deflected by neither electric fields nor magnetic fields.
