CloudLabs Converging Lens vs MorseLab

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.

Learn Morse code by rhythm, sound, and real practice. MorseLab helps you build Morse skill step by step with guided drills, audio decoding, speed rounds, digit practice, and a free-play tapping board. Start with dots and dashes, then grow into letters, words, numbers, phrases, and listening practice. Train across focused modes: Guided Training teaches Morse through clear word and sentence drills. Decode mode shows Morse patterns so you can type the English answer. Audio Decode trains your ear with Morse tones, letters, words, numbers, and short sentences. Numbers mode focuses on digit patterns from 0 to 9. Lightning mode pushes your speed with timed rounds and tighter rhythm. Playground lets you freely tap, hold, clear, delete, and experiment. Random Words gives you fresh practice prompts when you want variety. Customize timing, audio, and haptic feedback to match your pace. Track your progress with statistics for letters, signals, words, speed, recent sessions, and best times. Whether you are learning Morse code for the first time, practicing CW for ham radio, improving listening recall, or sharpening your tapping rhythm, Morse Code Lab gives you a clean, focused place to train.
