Question

An electric field $\vec{E}$ and magnetic field $\vec{B}$ exist in region. The field are not perpendicular to each other:

• A. This is not possible
• B. No electromagnetic wave is passing through the region
• C. An electromagnetic wave may be passing through the region
• D. An electromagnetic wave is certainly passing through the region

Answer 1

Answer: (C)

If $\vec{E}$ components are not perpendicular to $\vec{B}$ still electromagnetic waves can pass through this region
