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.
A wavelength is how far apart a crest or trough is from another crest or trough. In a wave, there are many different characteristics, which include its amplitude and frequency. the amplitude is the distance between a wave's mid-point and it's crest or trough. Mathematically :   wavelength of sound wave = speed of the wave / frequency   where   wavelength is measured in meters   speed is measured meters/second   frequency is measured is Hz or second-1. 4 people found this useful.
