App Description

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 not only easily visualize the relation of each variable in Planck-Einstein Relation, but also provides a calculator function, and allows sharing of data by AirDrop, Facebook account and others.

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.
- Users can take notes, and notes will be saved on the app permanently, unless deleted by users.
- Provides a calculator which is designed based on Planck-Einstein Relation.
- Provides a color-indicator to illustrate different wavelengths.
- Provides online reference to look up more detailed explanations of the Planck-Einstein Relation.
- Data produced in either the main view or the calculator view can be saved to the note tab and be shared with others.
- This app enables notes to share on a variety of means: AirDrop, Facebook, Message, email,etc.

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 ‘More Info’ tab to get detailed information regarding Planck-Einstein Relation, and to use the Notes function.
- To save data in both Main View and the Calculator View, press ‘Save’ button in respective views.
- To see and share the saved data, go to ‘More Info’ view, the data has been saved in the Notes section.
- To see the reference used for the Planck-Einstein Relation, click ‘Details’ button in ‘More Info’ view.
