1 Cover the cannula site with sterile transparent semipermeable occlusive dressing (e.g. Tegaderm, IV 3000) placed aseptically over the catheter. 2  If desired, place sterile tape over the hub and wings of the device before placing the transparent dressing.
Quick Answer. The difference between a long and short wavelength is the distance between two identical points on successive waves. Wavelength is also characteristic of the energy level of a particular wave, with shorter wavelengths being more energetic than longer ones. Continue Reading.
All types of waves, including tsunamis, have a wavelength, a wave height, an amplitude, a frequency or period, and a velocity. Wavelength is defined as the distance between two identical points on a wave (i.e. between wave crests or wave troughs).Normal ocean waves have wavelengths of about 100 meters. Wave velocity is the speed of the wave. 2  Velocities of normal ocean waves are about 90 km/hr while tsunamis have velocities up to 950 km/hr (about as fast as jet airplanes), and thus move much more rapidly across ocean basins. 3  The velocity of any wave is equal to the wavelength divided by the wave period.
