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. Let's break it down step by step:

### Step 1: Understanding Electromagnetic Waves
Electromagnetic waves consist of oscillating electric (E) and magnetic (B) fields that propagate through space. They do not carry a charge or mass.

### Step 2: Direction of Electric and Magnetic Fields
In an electromagnetic wave, the electric field and magnetic field are perpendicular to each other and to the direction of wave propagation. For example, if the wave is traveling along the z-axis, the electric field can be oriented along the x-axis and the magnetic field along the y-axis.

### Step 3: Force on Charged Particles
The force experienced by a charged particle in an electric field (E) and magnetic field (B) is given by the Lorentz force equation:
\[ F = qE + q(v \times B) \]
where:
- \( F \) is the force,
- \( q \) is the charge of the particle,
- \( v \) is the velocity of the particle,
- \( E \) is the electric field,
- \( B \) is the magnetic field.

### Step 4: Interaction of Electromagnetic Waves with Fields
Since electromagnetic waves are not charged, they do not experience a force due to electric or magnetic fields. Therefore, they cannot be deflected by these fields.

### Step 5: Conclusion
Based on the above reasoning, we conclude that electromagnetic waves are not deflected by electric fields or magnetic fields. Thus, the correct answer to the question is:
**Electromagnetic waves are deflected by neither electric field nor magnetic field.**

### Final Answer
**Option 4: Neither electric field nor magnetic field.**
