How is sound absorbed

You can see from this that the higher the frequency is, the lower the wavelength is . So, if you have a bigger energy jump, you will absorb light with a higher frequency – which is the same as saying that you will absorb light with a lower wavelength.

As wavelength is increased (or frequency decreased) the ultrasound will penetrate deeper. As the wavelength is decreased (or frequency is increased) the ultrasound beam will have a shallower penetration. Low frequency ultrasound has superior penetration. … FrequencyWavelength (l)5 MHz0.3 mm7 MHz0.2 mmSound Wave Properties – E-Echocardiography e-echocardiography.com › page › page

In addition, because absorption increases with frequency , it becomes very difficult for ultrasonic waves to penetrate a dense medium.
