Why do incandescent bulbs use glass as the bulb material?....
The matlab code structure below indexes substance materials according to their refractive values. The higher refractive values have higher light dispersion over a given area, and lower refractive values have lower light dispersion over a given area. Matlab Code: -Used to create a structure for a list of substances and their refractive values. clear all clc % Note: approximate indices of refraction for some materials % in the middle of the visible spectrum(600nm) % List of substances and refractive medium value in m/s materials_refrac.Air = 1.00; materials_refrac.Alcohol = 1.36; materials_refrac.Amber = 1.55; materials_refrac.CubicZerconia = 2.16; materials_refrac.Diamond = 2.42; materials_refrac.GlassAcrylic = 1.49; materials_refrac.GlassBorosilicate = 1.47; materials_refrac.GlassCrown = 1.52; materials_refrac.GlassFlint = 1.61; materials_refrac.Glycerin = 1.47; materials_refrac.Ruby = 1.76; materials_refrac.Salt = 1.50; materials_refrac.Vacuum = 1.00; materials_refrac.WaterIce = 1.31; materials_refrac.WaterLiquid = 1.33; What is the refractive medium value through a material?....
The matlab function code below calculates the refractive angle to your mediums. clc; clear; close all; refractive_media1 = input('Input first refractive media value: '); refractive_media2 = input('Input second refractive media value: '); Angle_of_entrance = input('Input the angle your light is entering from relative to your first media: '); Angle_of_refraction = abs((asin(refractive_media1*sin(Angle_of_entrance)/refractive_media2))*180/pi); disp('This is your refraction angle in degrees.'); disp(Angle_of_refraction) Matlab Code: -Used to calculate the refractive value for any substance created in the structure function[Rm] = RefracIndex(Cm) % constant for speed of light in m/s c = 2.99792 * (10^8); % calculation for refractive index through a medium Rm = c/Cm; end What do I do with this refractive media?
You can determine the angle of refraction by running this script:

How much lux does it take to light up a dim room?How to calculate lux.Copy, paste, and run this matlab script. You can compare your lux results to the table above.
clc;
clear; close all; lumens = input('Enter Amount of lumens: '); area = input('Enter Area in square meters: '); lux = lumens/area; disp(lux) Fluorescent vs. IncandescentIncandescent bulbs will soon become a thing of the past because the USA Lumens/Watt standard will com into effect.
