NEET · Physics · STD 12 - 8. Electromagnetic waves
The property which is not of an electromagnetic wave travelling in free space is that:
- A The energy density in electric field is equal to energy density in magnetic field
- B They travel with a speed equal to \(\frac{1}{\sqrt{\mu_0 \varepsilon_0}}\)
- C They originate from charges moving with uniform speed
- D They are transverse in nature
Answer & Solution
Correct Answer
(C) They originate from charges moving with uniform speed
Step-by-step Solution
Detailed explanation
The \(EM\) waves originate from an accelerating charge. The charge moving with uniform velocity produces steady state magnetic field.
