How far does sound travel in water? Well as we’ll see today, very loud sounds can travel hundreds of miles in water in a perfect (physics-style) environment. And in the ocean, due to sound wave reflection, sound can travel even…
Today we’ll be looking at how to measure sound waves and then we’ll discuss how to use those measurements to get the wavelength of those sounds. We’ll talk about two different tools we can use to measure sound (one is…
In short, wavelength determines the pitch of a sound wave. Sound waves with shorter wavelengths will have a higher pitch and sound waves with longer wavelengths will have a lower pitch. Now let’s break it all down. Speed, Wavelength and…
There are a handful of ways to measure sound frequency, but none are easier or cheaper than doing it with your phone. Today I’ll show you how I measured the frequency of my own voice using a free app called…
When a material encounters sound, it can do three different things with that sound: reflect the sound, let the sound pass through it, or it can transfer the sound into heat. Sound absorption refers to the last of these. Materials…
