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.
Waves can carry a little energy or a lot. They can be short or long. They can be rare or frequent. They can travel fast or slow. Sound waves, light waves, X-rays, microwaves, and ocean waves are but a few examples. All waves, however, share certain basic characteristics. All waves have amplitude, wavelength, and frequency. 1  In order to understand these characteristics of waves, it may help you to represent a wave as a drawing on a graph.
