Needs a little work

Buttons don't work to select from the environment and prism index libraries. It would also be nice to have the ability to change the wavelength of the laser.

Needs reflection

Put in the reflected angle.

Pretty nifty little application

As an Optical Engineer, I find this app an intriguing little tool just to use for showing my friends or illustrating something. Simple and yet very well done. The list of material refractive indices is very very complete. That alone makes it useful to have on me. Only thing I would want would be a few more prisms or maybe even the ability to create our own by dragging some handles around. Perhaps even prism unfolding, but that's just me being hopeful. Excellent for being free!

Awesome

It Seems like you copied IOR for the mass thing, but great job

Perfect!

This application is awesome. It computes then formulas quite accurately. It is definetly worth the purchase. It does exactly what it says it does!! Great job!!!!

FAQ

What is Prism Lab?

Prism Lab is a free educational application that simulates how lasers refract and reflect when passing through prisms. It uses Snell's Law to calculate the changes in light's trajectory as it moves between different environments.

How does Prism Lab work?

The app allows users to move a light source and observe how light interacts with various prism shapes and materials. It calculates entry and exit angles, demonstrating principles of reflection and refraction based on the properties of the materials involved.

Who would find Prism Lab useful?

Prism Lab is particularly useful for individuals studying physics or optics, including students and professionals. It provides a hands-on, visual way to grasp complex optical phenomena.

Does Prism Lab have ads?

No, Prism Lab does not contain advertisements. It is a free application without any in-app purchases or ad support.

What devices does Prism Lab support?

Prism Lab is available for iPhone and iPod devices. It is designed for iOS platforms.
