shift Humans have three types of cone cells in their eyes, which are responsible for color vision. Each type absorbs a certain part of the visible spectrum. Suppose a particular cone cell absorbs light with a wavelength of 542.nm. Calculate the frequency of this light. Round your answer to 3 significant digits.
