No what? No the speed of light in glass doesn't vary with frequency? No 
you don't understand? No you want to believe it's a mystery that science 
can't address, and will not accept any explanation that contradicts that 
view?

That follows directly from geometry if you accept the varying speed of 
light with frequency in glass.
