since ray stricks normally =90 degree to interface 

angle with normal =0 degrees and sin0=0  and sin i = n1 sin r 

then sin r must = 0 the r=0 degree with normal so light will go staright.

Dear student 
According to snell's law
Sin i/sin r= constant
Where i=angle of incidence
r=angle of refraction
When a light is incident on the interface of two transparent media then the angle of incidence and angle of refraction are zero.
