Which property is NOT true for electromagnetic waves travelling in free space?

Question

G1 Physics · Accepted Answer

Step 1: A propagating electromagnetic wave is generated by accelerated charges, not merely constant-speed charges. Step 2: In vacuum EM waves are transverse and travel at c = 1/√(μ₀ε₀). Step 3: Electric and magnetic components contribute equal energy density, so statement C is incorrect. Final answer: (C) They originate from charges moving with uniform speed.
