Explanation

• Cats have a unique audible range that is adapted to their hunting and communication needs.
• They can hear sounds in the range of 45 Hz to 64,000 Hz, which is wider than humans and dogs.

Explanation

Dogs can hear sounds in the range of 67 Hz to 45,000 Hz, which is slightly higher than the human audible range.

Explanation

• Whales have a unique audible range that is adapted to their underwater environment.
• They can hear sounds at very low frequencies, often below 20 Hz, and up to 31 kHz.

Explanation

Explanation

• The speed of sound in diamond is approximately 12,000 meters per second (m/s).
• It is one of the fastest speeds of sound among all materials.

The speeds of sound in different materials:

• Air: 343 m/s
• Water: 1433 m/s
• Wood: 3300-3600 m/s
• Brick: 4176 m/s
• Steel: 6100 m/s
• Diamond: 12000 m/s

Explanation

The velocity of sound in air at sea level under standard conditions (around 15°C or 59°F) is approximately 343 meters per second (m/s)

The speeds of sound in different materials:

• Air: 343 m/s
• Water: 1433 m/s
• Wood: 3300-3600 m/s
• Brick: 4176 m/s
• Steel: 6100 m/s
• Diamond: 12000 m/s

Explanation

• Sound travels slowest in air, with a speed of approximately 343 meters per second (m/s) at 20°C.
• This is because air is a gas and has a low density and stiffness, which allows sound waves to propagate more slowly through the material.

The speeds of sound in different materials:

• Air: 343 m/s
• Water: 1433 m/s
• Wood: 3300-3600 m/s
• Brick: 4176 m/s
• Steel: 6100 m/s
• Diamond: 12000 m/s

Explanation

• Frequency is the number of vibrations or oscillations produced by a vibrating body in one second.
• It's measured in Hertz (Hz), where 1 Hz equals one vibration per second.

Explanation

Decibel (dB) is the unit used to measure sound intensity.

Which is related to the amplitude of a sound wave.

The amplitude of a sound wave determines the loudness of the sound

One decibel (0.1 bel) equals 10 times the common logarithm of the power ratio.

Explanation

• Amplitude is the maximum displacement of a wave from its equilibrium position.
• It is the distance from the rest position to the top of a crest or the bottom of a trough.
