What is the value of the sin i sin R ratio for glass and air?
The ratio of sin i to sin R, known as Snell's law, can be expressed as sin i / sin R = n₂ / n₁, where n₁ is the refractive index of air (approximately 1) and n₂ is the refractive index of glass (typically around 1.5). Therefore, for light transitioning from air to glass, the value of sin i / sin R is approximately 1 / 1.5, or 2/3. This ratio illustrates how light bends when entering a denser medium.
What is the r value of glass block?
The R-value of glass block typically ranges from 1 to 2, depending on factors such as thickness and the specific type of glass used. This measurement indicates the material's resistance to heat transfer, with higher values representing better insulation. While glass blocks provide some insulation, they are generally not as effective as traditional insulating materials like fiberglass or foam. For energy efficiency, it's essential to consider additional insulation methods when using glass blocks in construction.

How do you find the r value of a r square value?
To find the Pearson correlation coefficient (r) from the R-squared (R²) value, you simply take the square root of R². If R² is positive, r is the positive square root of R²; if R² is negative (which is not possible since R² ranges from 0 to 1), r would be negative. Thus, the formula is r = ±√R², where the sign depends on the direction of the relationship (positive or negative correlation).
How do people walk on water?
People use plexi glass in water and walk on that and that plexi glass is invisible in water.

How do you spell plexi glass?
Generally speaking, plexiglass is written as a single word - though otherwise you have spelt it correctly.
Which material has the highest r value stucco pine board concrete or fiber glass insulation?
Fiberglass Insulation, R Value of 3.14. Pine board has an R Value of 1.74
What are the best material for garage door windows to be made out of?
Ideally, you don't want regular glass in a garage door, as the door closing hard could shatter them. You would be better off using either tempered glass or plexi-glass.
Does concrete have an R value. 8 inches is equal to about a single pane of glass. Not much at all...?
Yes. Don't know for sure but its pretty low. however note that R value depends on the thickness. You double the thickness you double the R value.
