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.
The difference is that with the longer wavelengths, the lower the frequency and the speed of the waves will be. The smaller the wavelength is, the higher the frequency and the speed will be. Wavelength is measured by the distance between two spectrums (the highest point on the wave)
