What type of wave is sound? Circle all correct: Mechanical Electromagnetic Transverse What is pitch related to? What is the loudness of a sound related to? What happens to the frequency of a moving sound as it gets closer to you? What happens to the frequency of a moving sound as it gets further away from you? How does temperature affect the speed of sound? Sound waves travel differently through gas (like air), liquids (like water) and solids. In which medium does sound travel the fastest?

Let's break down your questions step by step: 1. **What type of wave is sound?** - Sound is a **Mechanical** wave. It requires a medium (solid, liquid, or gas) to travel through. - It is not an **Electromagnetic** wave, as electromagnetic waves (like light) do not require a medium. - Sound waves are also not **Transverse** waves; they are primarily **Longitudinal** waves, where the particle displacement is parallel to the direction of wave propagation. 2. **What is pitch related to?** - Pitch is related to the **frequency** of the sound wave. Higher frequency sounds are perceived as having a higher pitch, while lower frequency sounds are perceived as having a lower pitch. 3. **What is the loudness of a sound related to?** - Loudness is related to the **amplitude** of the sound wave. Greater amplitude results in a louder sound, while smaller amplitude results in a softer sound. 4. **What happens to the frequency of a moving sound as it gets closer to you?** - As a sound source moves closer to you, the frequency of the sound increases. This phenomenon is known as the **Doppler effect**. 5. **What happens to the frequency of a moving sound as it gets further away from you?** - As a sound source moves away from you, the frequency of the sound decreases, also due to the **Doppler effect**. 6. **How does temperature affect the speed of sound?** - The speed of sound increases with an increase in temperature. This is because warmer temperatures provide more energy to the molecules in the medium, allowing them to vibrate and transmit sound waves more quickly. 7. **In which medium does sound travel the fastest?** - Sound travels fastest in **solids**. The speed of sound is generally slower in liquids and slowest in gases. This is due to the closer proximity of particles in solids, which allows for quicker transmission of sound waves. In summary: - Sound is a **Mechanical** wave. - Pitch is related to **frequency**. - Loudness is related to **amplitude**. - Frequency increases as the sound source gets closer and decreases as it moves away. - Speed of sound increases with temperature. - Sound travels fastest in **solids**.
