About

CloudLabs Converging Lens

Features
Read full description

This simulator recreates an optical table with a converging lens and two test objects. The goals of this lab are to experimentally find the focal length, radius of curvature, and power of the lens, as well as find the magnification of the image and determine whether or not it is inverted. During the laboratory development you will be able to observe the changes in the size of the formed image, as the distance between the object and the lens is varied.

Verdict

The call

The clearest difference is in-app purchases: CloudLabs Converging Lens at none against RayLab's 10. CloudLabs Converging Lens also leads on ads (none vs shown) and iOS requirement (9.0 vs 11.0). RayLab's advantage is update cadence (every 6 weeks vs every 21 months). On price and device support there is nothing between them.
