Learning Task 4
Answer the ff. questions:
1.In which medium can sound wave travel faster?
2.How do sound travels through air? What do we call to the reflected sound back to its source?
3. What affects the speed of sound as it travels?
4.The back and forth movement of sound is called_________.
5.What do we call to the imaginary waves when an object vibrates?
6.When the sound travels through solids, the vibration of the particles occurs?
Sound waves travel faster and more effectively in liquids than in air and travel even more effectively in solids.
When a drum is hit, the air particles next to the drum skin vibrate and collide with other particles, and this vibration is then transmitted through the air. This is known as wave compression, which allows sound to travel quickly through the air.
The speed of sound is a term used to describe the speed of sound waves passing through an elastic medium. ... The speed varies depending on atmospheric conditions; the most important factor is the temperature.
Sound waves are called longitudinal waves because the particles move back and forth in the direction of the wave movement.
In electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields.
Sound waves need to travel through a medium such as solids, liquids and gases. The sound waves move through each of these mediums by vibrating the molecules in the matter. The molecules in solids are packed very tightly. ... This enables sound to travel much faster through a solid than a gas.
