- Why does a sculpture three dimensional?Calculate the critical angle for a flint glass-air boundary. (hint: Use table of indices of refraction if necessary).A soda straw is stuck into water at an angle of 36° to the vertical. Looking straight down, what does the angle of the submerged portion of the straw to the vertical appear to be?
