The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question states that a ticking clock sound is heard late when heard through a metal. We need to analyze whether this statement is true or false. 2. **Properties of Sound**: Sound travels through different mediums (solids, liquids, and gases) at different speeds. The speed of sound is generally highest in solids, lower in liquids, and lowest in gases. 3. **Behavior of Sound in Solids**: In solids, particles are closely packed together. This close packing allows sound waves to transmit vibrations more efficiently compared to liquids and gases. 4. **Conclusion on Sound Transmission**: Since sound travels faster in solids due to the close packing of particles, a ticking clock sound would actually be heard earlier when transmitted through a metal (a solid) rather than later. 5. **Final Statement**: Therefore, the statement that a ticking clock sound is heard late when heard through a metal is false. In reality, we hear the ticking sound earlier through metal. ---
