Coulter principle. - Answer-The ability to count and measure the size of particles using an electric 
circuit. Particles are moved through a small aperture, their presence causes a narrowing of the 
aperture, which leads to an increase in resistance.By using constant I, According to Ohms law (U= I * 
R), when R increases, U increases and pulse is generated. 
Parts and functions of the Coulter-counter - Answer-- Two spaces with a small aperture in between, 
capillary (contains the electrolyte sol...

Describe the relationship between the frequency, wavelength, and velocity (speed) of a wave. 
The more times the wave is passing through a point in space = a higher frequency, the higher 
frequency creates a smaller wavelength, which is why the smallest wave is a gamma wave, it has 
the highest frequency and the shortest distance between waves, the velocity can be measured in 
m/s and is composed of frequency and wavelength
