Lambda max refers to the wavelength along the absorption spectrum where a substance has its strongest photon absorption. Scientists can then use lambda max as a parameter to compare the different qualities of all types of molecules and substances. can trickle chargers be left on

"WebDepending on the type of wave, wavelength can be measured in meters, centimeters, or nanometers (1 m = 10 9 nm). The frequency, represented by the Greek letter nu ( ν ), is the number of waves that pass a certain point in a specified amount of time. Typically, frequency is measured in units of cycles per second or waves per second. " - How to determine analytical wavelength
