Understanding Wave Propagation
When discussing wave propagation, it is essential to understand the medium through which different types of waves travel. Here’s a breakdown of the options presented in the question:
Sound Waves
- Sound waves are mechanical waves.
- They require a medium (solid, liquid, or gas) to propagate.
- Without a medium, sound cannot travel (e.g., sound cannot travel in a vacuum).
Light Waves
- Light waves are electromagnetic waves.
- They do not require any medium for propagation.
- Light can travel through a vacuum, such as space.
Radio Waves
- Like light waves, radio waves are also electromagnetic waves.
- They can propagate through a vacuum and do not need a medium.
- This characteristic allows radio signals to travel long distances through space.
Water Waves
- Water waves are mechanical waves.
- They require water (or another fluid) as a medium to propagate.
- These waves cannot exist in a vacuum.
Correct Answer Explanation
Based on the analysis:
- Sound waves and water waves require a medium.
- Light waves and radio waves do not require a medium.
Thus, the correct answer is option B: (b) and (c) are correct, indicating that both light waves and radio waves do not require a medium for propagation.
