NEET Physics Properties of EM Waves MCQ Question
Which of the following statements about electromagnetic waves is correct?
Electromagnetic waves travel at different speeds depending on their frequency.
Accelerating charges can produce electromagnetic waves of the same frequency as the charge's oscillation.
Electromagnetic waves with longer wavelengths interact more strongly with matter than those with shorter wavelengths.
Hertz's experiments only demonstrated the production of electromagnetic waves in the ultraviolet region.
Correct Answer
Detailed Explanation
Accelerating charges indeed radiate electromagnetic waves of the same frequency as their oscillation, as stated in the NCERT context. The speed of electromagnetic waves is constant in vacuum for all frequencies, and longer wavelengths do not necessarily interact more strongly with matter.
