Options

A. Statement-1 is True, Statement-2 is True-2 is True , Statement-2 is a correct explanation for Statement-7
B. Statement-1 is True, Statement-2 is True-2 is NOT a correct explanation for Statement-7
C. Statement-1 is True Statement-2 is False
D. Statement-1 is False, Statement-2 is True

Answer

To analyze the statements given in the question, we can break down the problem step by step.

### Step 1: Analyze Statement 1
**Statement 1**: The ratio of magnitudes of the electric field (E) to the magnetic field (B) in an electromagnetic wave is constant.

- In electromagnetic waves, the relationship between the electric field and the magnetic field is given by the equation:
\[ \frac{E}{B} = c \]
where \(c\) is the speed of light in vacuum, approximately \(3 \times 10^8 \, \text{m/s}\). This ratio is indeed constant for all electromagnetic waves.

**Conclusion**: Statement 1 is true.

### Step 2: Analyze Statement 2
**Statement 2**: The electric field and magnetic field are always in the same phase in an electromagnetic wave.

- To understand this, we need to consider the nature of electromagnetic waves. In an electromagnetic wave, the electric field and magnetic field oscillate sinusoidally and are oriented perpendicular to each other and to the direction of wave propagation.
- The term "same phase" means that the peaks (maxima) and troughs (minima) of the electric field and magnetic field occur at the same points in space and time. This means that when the electric field reaches its maximum value, the magnetic field also reaches its maximum value simultaneously.

**Conclusion**: Statement 2 is true.

### Final Conclusion
Both statements are true. The ratio of the magnitudes of the electric field to the magnetic field in an electromagnetic wave is constant, and the electric and magnetic fields are always in the same phase.
