I always wanted to do simple calculations in HTML and create simple online equation solvers. I spent some time on it and have created a simple equation solver. I have include the code here with lots of comments to try and help others who might want to learn. The biggest issue I had was with the button. I had to use a form input of type button rather than a button element (<button></button>)....

Refractive Index of Water

Due to the effects of optical dispersion, the refractive index of water is dependent on the wavelength of light being used. After a long search, I found a good reference for this information (Daimon and Masumura). here is a plot of their data in the visible range:
Matlab was used to fit a exponential decay function to the 20oC data:
y...

Calcium Chloride (CaCl2) Useful Information

Refractive Index
Refractive index is a bulk material property. This property has a real and imaginary part and is dependent on wavelength. The real part describes how light "slows down" or "scatters" in a material and the imaginary part indicates how the material adsorbs light.
Typically, a single real value of refractive index will be...

LGRIN Lens
Mao, X., et al., Lab Chip, Vol. 9, pp. 2050-2058 (2009).
We report a tunable optofluidic microlens configuration named the Liquid Gradient Refractive Index (L-GRIN) lens for focusing light within a microfluidic device. The focusing of light was achieved through the gradient refractive index (GRIN) within the liquid medium, rather than...
