How deep can ultrasound penetrate

Penetration depth is a measure of how deep light or any electromagnetic radiation can penetrate into a material. It is defined as the depth at which the intensity of the radiation inside the material falls to 1/e (about 37%) of its original value at (or more properly, just beneath) the surface. When electromagnetic radiation is incident on the surface of a material, it ma… WebDeep Penetration: What It Is. For some, penetration during sex is even more enjoyable when it’s very deep.
