Refractive vs Electromagnetic Forces
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Refractive
This application calculates the refractive index of transparent materials based on wavelength. It assists optical design engineers and students by computing transmission properties, angles, and critical values. Users can also define custom materials for their calculations.
- Refractive index calculation by wavelength
- Light transmission angle calculation
- Reflection and transmission coefficients
- Critical angle and Brewster's angle calculation
- Recall of refraction formulas
- Custom material definition

Refractive is a software that calculates the refractive index of the major transparent materials in accordance to wavelength. Refractive is conceived for Optical design engineers as well as students interested in optics. All that’s needed is to select two materials to calculate their transmission proprieties. Characteristics : - Calculation of the refractive index according to wavelength; - Calculation of light’s transmission angles; - Reflection and transmission coefficients for the two materials in accordance to the angle of incidence; - Calculation of the critical angle and Brewster’s angle,; - Recall of the major refraction formulas; - Possibility to define personalized materials.

Electromagnetic Forces physics app has been designed for K12 students to describe the process of magnetic effect and magnetic force of current. This app helps students to learn about Fleming’s left-hand rule and describes cathode rays structure in an interactive way. In addition, the electromagnetic Forces app illustrates the uses of Cathode Ray Oscilloscope through 3D animations. Each section is explained in detail with diagrams, graphical representations and animations along with simple text explaining the concept. Features of Electromagnetic Forces App: Learn -This section describes the overall process of Electromagnet and Cathode Ray Oscilloscope with 3D animations. Electromagnet - An electromagnet experiment using a wire & Fleming’s left-hand rule to check magnetic effect and magnetic force of current with interactive 3D animations. Cathode rays - In this, cathode rays experimented through CRO (cathode ray oscilloscope) using electromagnetic forces process in an interactive way. 2) Practice - This section helps to practice the working process of electric motor and also observe the variations in sine wave graph with animated 3D experiments. 3) Quiz - Evaluate the knowledge gained from Electromagnetic Forces application through an interactive quiz with scoreboard. This educational application helps students to understand electromagnet and cathode rays in an easy and quick method through interactive animations and experiments. Download the Electromagnetic Forces app and other K12 education apps published by Ajax Media Tech Pvt Ltd to learn physics in an easy and interactive way. Unlike a static or video based education model, which is non-interactive, K12 simulator apps are fully interactive and developed based on adaptive learning.
