Why does light not bend when the incident ray is perpendicular to the surface of glass,and instead,will pass through it without bending

What does Snell's law say?

[Sigmarus]

Well i haven't learnt about Snell's law yet :/

Snell's Law states that the ratio of the sine of the angle of incidence to the sine of angle of refraction is a constant for a given medium.
