white

When all visible wavelengths of light transmitted is combined _____ light results

Frequency

is the number of vibrations of wave motion per second

inversely

The wavelength is _________ related ti frequency and energy.

higher

the shorter the wv, the ____ the freqency and energy vice versa

h = Planck’s constant v = frequency

colorimetry

Measurement of the amount of light absorbed by a colored solution

photometry

measurement of light WITHOUT specifying a wavelenght

spectophotometry

measurement of light at a SPECIRFIC wavelenght
