Speed of sound
In this Class 9 Science topic, students learn how fast sound travels through different media and why its speed changes in solids, liquids, and gases. They explore the relationship between distance, time, and speed using the formula v = d/t, and examine how temperature affects sound propagation in air. The topic also connects speed of sound with everyday observations such as echoes, communication, and the design of sound-based instruments.
