A narrow light ray in air strikes a flat boundary with glass at an incident angle of 40∘40^\circ measured from the normal. The glass has a higher refractive index than air (nglass>nairn_{glass} > n_{air}). Ignoring reflection, the ray enters the glass at the point of incidence. Which way does the ray bend as it crosses into the glass?
