Is there an algebraic formula for determining an angle of reflection using only the angle of the ray and the angle of the wall?
Let r be the angle of the ray, and R the angle of reflection.If the wall is flat (i.e., if its angle is 0), then we know that r + R = Pi/2.Now suppose the wall has angle w. Then rotate the diagram by -w,so that the wall is now flat again, and the angles of the ray and itsreflection are now r - w and R - w, respectively.We then have (r - w) + (R - w) = Pi/2, which should give you enoughinformation to find R.

What is g equals rz for r?
In the equation g = rz, r represents a variable or a constant value. The specific value of r would need to be provided in order to determine its numerical value in the equation.

How thick is r 5?
"R" is a value associated with heat penetration. The thickness of a material (for example, typical pink panther insulation) of any "R-value" will vary. If, for example, your wall space involves either a 2"x4", 2"x6", or even 2"x8" wall space then the material you insulate with will, of course, vary in size, however the "R-value" of your material will remain its rated value.

How thick a concrete wall would be needed to give the same insulating value as 3 and a half inches of fiberglass?
To provide the same insulation value as 3.5 inches of fiberglass, a concrete wall would need to be approximately 15-18 inches thick. Concrete is a poor insulator compared to fiberglass, so a much thicker wall is needed to achieve similar insulation properties. Alternatively, adding insulation material within the concrete wall can help improve its insulating capabilities.
Why does a wall cavity with a reflective surface have a higher R-value?
A wall cavity with a reflective surface has a higher R-value because the reflective surface reduces radiant heat transfer by reflecting heat back towards its source, thus improving the thermal performance of the wall assembly. This can help reduce heat loss in the winter and heat gain in the summer, making the insulation more effective overall.

Is dry wall an insulator?
While drywall, or gypsum board, does give insulation value it is not a high amount, a 1/2" piece of drywall will only raise the r-value by .45, if you are looking to improve the insulation of a wall you are much better off using rigid foam insulation. An extruded polystyrene board, that's Styrofoam, of 1" thickness gives you an R-value of 5.00, which is over 5 times greater per inch than that of drywall. You can further improve the insulation value of a wall by add some kind of batt insulation in-between the studs.
