A free app for Android, by Learners Series.

The app is an educational tool for students or anyone interested in the field of optical science and its applications. It provides information on various topics such as the reflection and transmission of light, the formation of images by a mirror, the laws of reflection and transmission, the relation between the focal length and the radius of curvature, the law of distances, the mirror equation, the magnification, the linear magnification, the reflection and transmission of light, the total internal reflection, the critical angle, the application of the total internal reflection, the lenses, the focal length, the focal plane, the image formation, the images formed by a convex lens, the image formed by a concave lens, the relation between the radius of curvature and the focal length, the scattering of light, the rayleigh scattering law, the raman scattering, the application of the raman scattering, the polarisation of light, the anisotropic scattering of light, and the application of the anisotropic scattering of light.

The app includes an analysis with formulas of the optical parameters, and this is done to help you to study the above-mentioned topics.
