In National 4 Physics examine the properties of waves and use the wave equation, v = f λ, to relate the speed, frequency and wavelength.

In this article, we have experimentally demonstrated a laser Doppler velocimetry (3D-LDV) system capable of measuring 3-D flow velocities, employing a single emission wavelength and four ...

In several clinical studies, the velocity of the first arriving signal (FAS) measured in axial transmission on various skeletal sites was shown to be a robust ultrasound parameter able to discriminate ...
