The amount of scattered light is defined by I = kNV^2/y^4, where k is a
proportional constant, N is the number of particles, V
is the volume of one particle, and y is the wavelength of the light.
Since the wavelength is in the denominator alone (but to the 4th power), any
difference in Tyndal due
Good point. I guess a full spectrum laser would have to be used to detect
proportions of whatever sized particles.
Not too darned easy.

Considering that the tyndall goes up by the 4th power of the size, it would be
impossible to measure any ppm unless you knew the size and all the particles
were the same.

Its not hard. Just shine the beam through the water perpedicular to your
line of vision. Distilled water does not show a beam. CS, unless totally
ionic, does. Ions are too small to reflect that wavelength of light. The
higher the ion to colloid ratio, the brighter the beam. If the CS is highly
Hey Ken,
Do you have a source that explains how to properly use the laser pointer?
Thanks. Ric
