LearnLight Spectrometry
APP OF THE MONTH: LearnLight Spectrometry
OFFERED BY: Flappit.com
PLATFORMS: iOS 4.3 or later (compatible with iPad),Android
WHAT IT DOES: LearnLight is designed to allow users to compare any of five included spectral images and plot their visible light intensity, transmittance, and absorbance. The app reportedly teaches users about visible light, spectrometry, spectroscopy, and spectrophotometry. According to the company, users can set one image as a reference and another as a sample; observe how altering width (in pixels) of a given selection changes the resulting data; compare the relative intensities of blue, red, and green light energy; and find the relationship between transmittance and absorbance.
