Question

An electromagnetic wave going through vacuum is described by: \[ E = E_0 \sin(kx - \omega t) \] Which of the following is/are independent of the wavelength?

• A. \( k \)
• B. \( \omega \)
• C. \( E_0 \)
• D. \( k_0 \)

Hint:

The amplitude \( E_0 \) of an electromagnetic wave is independent of its wavelength and frequency.

Answer 1

The Correct Option is C

Step 1: Understand the relationship of parameters.
The wave vector \( k \), angular frequency \( \omega \), and the amplitude \( E_0 \) are related to the wavelength and frequency, but \( E_0 \) is independent of the wavelength.
Step 2: Explanation.
The electric field amplitude \( E_0 \) does not depend on the wavelength or frequency of the wave.
Final Answer: \[ \boxed{E_0} \]
