Electromagnetic Waves

Question:

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:

Options:

A, B and C only

B, C and D only

C, D and E only

A, D and E only

Correct Answer:

C, D and E only

Explanation:

The correct answer is Option (3) → C, D and E only

(C) Since X-rays have much higher frequencies than visible light, their energy is indeed greater.

(D) Radio waves are typically produced by the oscillation of electric charges in conductors such as antenna.

(E) An oscillating electric dipole is a fundamental source of electromagnetic radiation.
