Explanation

• Vibration refers to the rapid back and forth movement of an object, often in a repeating pattern.
• This can include motions like oscillations, shakes, or tremors.

Explanation

• When sound travels through air, the air particles vibrate back and forth along the direction of wave propagation.
• This means that the air particles oscillate in the same direction as the sound wave is traveling.
• It allowing the energy of the sound wave to be transmitted through the air.

Explanation

• When sound waves reach the ear drum, it vibrates and causes the small bones (ossicles) behind the eardrum to vibrate.
• These vibrations are then transmitted to the liquid in the inner ear (cochlea).
• Where they are detected by small hairs (hair cells) and converted into electrical signals that are sent to the brain via the auditory nerve.

Explanation

• The speed of sound in aluminium is approximately 6420 meters per second.
• It is significantly faster than the speed of sound in air due to aluminium's higher density and elastic properties.

The speed of sound in different materials:

• Air: 332 m/s
• Sea water: 1530 m/s
• Lead: 2160 m/s
• Gold: 3240 m/s
• Brick: 3650 m/s
• Copper: 4760 m/s
• Glass: 5100 m/s
• Aluminium: 6420 m/s

Explanation

• The speed of sound is maximum in gold, with a value of approximately 3240 meters per second (m/s).

• Aluminium: 6420 m/s

Explanation

• The speed of sound is minimum in gases because the particles are farthest apart, resulting in a slower transmission of vibrations.
• In gases, the speed of sound is approximately 343 meters per second at room temperature and atmospheric pressure.

Explanation

• The speed of sound is maximum in solids.
• Because the particles are closely packed, allowing for efficient transmission of vibrations.

Explanation

• In a longitudinal wave, a rarefaction is a region where the particles are furthest apart.
• This is in contrast to a compression, which is a region where the particles are closest together.

Explanation

• In a longitudinal wave, a compression is a region where the particles are closest together.
• While a rarefaction is a region where the particles are farthest apart.
