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 properties of these waves differ quite considerably. Sound waves travel a million times slower than light waves. They have wavelengths between 1 centimetre and 10 metres, and will easily diffract round corners. Light waves have much smaller wavelengths, and only diffract through very small holes.
