Refraction through a Prism

In optical, the refraction is happened when the light passes through one medium with the specified refractive index to the other medium, it is with an angle. The waves phases velocity is altered at the end of the boundaries between the media, so usually causing a change in the direction of light. Even though the frequency is constant but its wavelength increases or decreases . If the change in refractive index, the light rays will refract is changed as it enters and leave the glass prism. The light ray traveling is perpendicular to the boundary of prism will the change the speed of light but light ray does not change the direction.
