Visualize Wavelength Equation

The Wavelength app is designed to help students learn Planck-Einstein Relation, especially for first-year science and engineering students and high school students. Specifically, this app provides multiple features to enable students to easily visualize the relation of each variable in Planck-Einstein Relation, and also provides a calculator function. Features - Useful particularly to beginning science or engineering students and high school students. - Can also be used by researchers who need to quickly convert between relevant units - Intuition building- as energy goes up, frequency goes up, and wavelength goes down. - Using slider bars, users can visualize the relation between energy, wavelength and frequency, and to see the type of electromagnetic radiation it belongs to. - Provides a calculator which is designed based on Planck-Einstein Relation. - Provides a color-indicator to illustrate different wavelengths. How to Use the App - Press ‘Main View’ tab to visualize the the change of the three variables (energy, frequency, wavelength) associated with the Planck-Einstein Relation. - Drag the slider bars, and values will change accordingly. - Press ‘Calculator’ tab to calculate energy, wavelength or frequency, based on the user input. - Press ‘Info’ tab to get detailed information regarding Planck-Einstein Relation, and to use the Notes function.
