Maxwell decides to use a laser to catch Shadow, since he read on the internet that cats like to chase lasers. He shines a red laser through a glass window at Shadow’s face. However, the light reflects off the window instead. What phenomenon did Maxwell forget to account for? What is the critical angle for this phenomenon at the glass/air interface?

in the above said process , maxwell forgot to account for the snell's law of refraction which tells us about the deviation of light from its original path after travelling from one medium to another with with a different refractive index.
mathematically :
the light bounces back into the medium if the angle of incidence is greater than the critical angle for a given pair of media.
