Question

What are two common units used for measuring the wavelength of light?

Answer 1

Answer: Light is measured in many units. Its wavelength, λ, is measured in both ngstroms and nanometers. Its frequency is measured in Hertz.

Explanation:

Answer 2

Angstroms and Nanometers

---------------------------------------

Angstroms: "a unit of length equal to one hundred-millionth of a centimeter, 10−10 meter, used mainly to express wavelengths and interatomic distances."

-

Nanometers: "Wavelengths of visible light are measured in nanometers (nm). A nanometer is a unit of length equal to one billionth of a meter."
