it is the ray produced when the light ray fall on a medium with angle=90 and this ray produced becomes a tangent to the separating surface.
x-ray
Grazing emergence occurs when the incident ray is makes an angle between itself and the normal which is equal to the critical angle (42 for glass).
X-ray telescopes use grazing incidence to focus X-ray photons onto a detector. By reflecting the X-rays at a very shallow angle, these telescopes can overcome the limitations faced by traditional optical telescopes in detecting X-ray emissions from astronomical sources.
Free range originally meant unfenced cattle grazing lands.

If you meant glasses, then Ray Bans are great.
In "The Gift" by Ray Bradbury, the boy did not actually receive the gift that was meant for him. The gift, a rocket, ended up exploding when his parents tried to test it out for him.
grazing incidence optics... x rays cannot be treated the same as visible light... it is not filtered but focused
the term world ocean is meant by the world being covered by mostly the ocean. -Denzel -Ray Allen
The cows are contentedly grazing on the hillside. My shots are just grazing my targets.
Your not meant to understand
90 degrees is the largest possible angle of incidence because it is then parallel to the face of the mirror and is grazing the mirror.
