Which of the following statements about electromagnetic waves is/are correct?
A. Visible Light can be polarised but X-rays cannot.
B. X-rays in vacuum travel faster than visible light waves in vacuum.
C. The energy of X-ray photon is greater than that of a visible light photon.
D. Radio waves are produced by the accelerated motion of charges in conducting wires.
E. An electric dipole is a basic source of electromagnetic waves.
Choose the correct answer from the options given below:
- A A, B and C only
- B B, C and D only
- C C, D and E only
- D A, D and E only
Answer & Solution
Correct Answer
(C) C, D and E only
Step-by-step Solution
Detailed explanation
(C) Correct: \(X\)-rays have a much higher frequency than visible light. According to \(E=h f\), the energy of an X-ray photon is significantly greater. (D) Correct: Radio waves are typically generated by accelerating electrons (oscillating charges) within an antenna or…
