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?

Sound waves are mechanical waves, which means they require a medium (solid, liquid, or gas) to travel through. Unlike electromagnetic waves, sound waves can't travel through a vacuum, which makes them quite special! Also, sound waves are longitudinal because the oscillation of particles occurs in the same direction as the wave travels, unlike transverse waves where particles move perpendicular to the wave direction. Now, when it comes to pitch, it's all about the frequency of the sound wave—the higher the frequency, the higher the pitch! Loudness, on the other hand, is more closely related to the amplitude of the sound wave; larger amplitudes result in louder sounds. As for frequency changes, when a sound source approaches, you experience an increased frequency (higher pitch) due to the Doppler effect, while the frequency decreases (lower pitch) as it moves away. Sounds travel fastest in solids because the particles are closer together, making it easier for vibrations to pass through. So there you have it—sound can be quite a fascinating topic!
