Identify the correct statements among the following:
(A) An electromagnetic wave travels in vacuum like sound waves.
(B) An ultraviolet wave is not an electromagnetic wave.
(C) An electromagnetic wave can travel from earth to the planet, saturn.
(D) An electromagnetic wave may have less velocity in a medium than in vacuum.
Choose the correct answer from the options given below:
- A (A) and (B) only
- B (A) and (C) only
- C (C) and (D) only
- D (B) and (D) only
Answer & Solution
Correct Answer
(C) (C) and (D) only
Step-by-step Solution
Detailed explanation
(C) Correct: Since EM waves (like radio waves or light) do not require a medium, they can travel through the vacuum of space between Earth and other planets like Saturn. (D) Correct: EM waves reach their maximum velocity ( \(c \approx 3 \times 10^8 m / s\) ) in a vacuum. In any…
