The correct Answer is:
To solve the question, we need to analyze both statements provided: **Step 1: Analyze Statement 1** - The statement claims that the CGS unit of amplitude is Maxwell. - Amplitude in physics typically refers to the maximum extent of a vibration or oscillation, measured from the position of equilibrium. In the context of waves, amplitude is often associated with the height of the wave. - In the CGS (Centimeter-Gram-Second) system, the unit of length is the centimeter (cm), not Maxwell. The term "Maxwell" is actually a unit of magnetic flux, not amplitude. - Therefore, Statement 1 is **incorrect**. **Step 2: Analyze Statement 2** - The statement claims that electromagnetic (EM) waves require no medium to propagate. - Electromagnetic waves, such as light, radio waves, and X-rays, can travel through a vacuum as well as through various media (like air, water, etc.). They do not require a medium to propagate, which is a fundamental property of EM waves. - Therefore, Statement 2 is **correct**. **Conclusion:** - Statement 1 is incorrect, and Statement 2 is correct. - The correct option is that only Statement 2 is true.
