In ultrasonic testing, higher frequencies typically result in:

In ultrasonic testing (UT), higher frequencies are associated with better resolution. This occurs because a higher frequency signal generates shorter wavelengths. Shorter wavelengths can more effectively distinguish between closely spaced flaws or features within a material. As a result, when inspecting intricate structures or small defects, higher frequencies allow for finer detail and a clearer representation of the internal characteristics of the material being tested.

Moreover, while higher frequencies do provide improved resolution, they also lead to increased attenuation. This means that higher frequency signals are absorbed more quickly by the material, which can limit the depth of penetration. Therefore, although higher frequencies enhance resolution, they do not penetrate as deeply compared to lower frequencies. Additionally, longer wavelengths are characteristic of lower frequencies, making that relationship distinct.
