A student holds two pieces of paper at the top, 10 cm apart. The flat sides of the papers face each other. What happens when the student uses a straw to blow a stream of air between the papers?

The index of refraction of silicate flint glass for red light is 1.620 and for violet light is 1.660. A beam of white light in this glass strikes the glass-air interface at a 25.50∘ angle of incidence and refracts out into the air.
