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 wave with a large amplitude will be particularly tall, and a wave with a small aptitude will be particularly short. It turns out that the amplitude tells you how much energy is in the wave. A high amplitude wave is a high-energy wave, and a low-amplitude wave is a low-energy wave. In the case of sound waves, a high amplitude sound will be loud, and a low amplitude sound will be quiet. Or with light waves, a high amplitude beam of light will be bright, and a low amplitude beam of light will be dim. But amplitude isn't the only factor that affects the energy of a wave. The other factor is frequency.
