* base line * orthogonal projection * Versine co-ordinate The above may (or may not; the first two seem wrong and I don't think I've ever heard of the third) be correct, but I suspect the term you're looking for is surface normal or normal vector.

∙ 6y agoAt the point of incidence where the ray strikes the mirror, a line can be drawn perpendicular to the surface of the mirror. This line is known as a normal line(labeled N in the diagram). The normal line divides the angle between the incident ray and the reflected ray into two equal angles.

What is the angle of incidence equivalent to?
Snell's law equates the ratios of two angles and wave velocity.sin(a)/V1 = sin(b)/V2When a wave strikes a medium some energy is reflected and some passes through.a is the angle between the longitudinal wave velocity of the wave in the first medium as measured from a perpendicular to the tangent of the surface of the medium.b is the angle between that perpendicular and the longitudinal wave as it is refracted within the medium.The angle of incidence refers to these angles.Clearly, if the wave strikes perpendicular to the surface, a = b = 0 and sin(a) = sin(b) = 1
How does light travel when the medium it travels through changes and how does light travel when the medium does not change?
Light travels in straight lines when the medium's density is constant. When light enters a different density perpendicularly, it also travels in a straight line. When light enters a higher density at an angle, it bends towards an imaginary line perpendicular to its pont of entry. When light enters a lower density medium, it bends away from the imaginary perpendicular line. This is seen with objects partially submerged in water. The light exits the water and bends away from its normal path, making the object appear crooked in relation to the unsubmerged portion. Sometimes light will be reflected at the boundary of two mediums. This is seen in optic fibres.
Why perpendicular light rays don't refrect through a medium?
As it is parallel to the normal to the surface, the angle of incidence is zero and hence the angle of refraction also has to be zero. Hence no deviation and no refraction.
Why does a stick dipped in water appears to be bent?
Light bends when it passes at an angle into a medium of a different density. When light passes from a less dense medium into a denser medium, like from space into Earth's atmosphere or from air into water, it bends toward the normal, which is an imaginary line perpendicular to the boundary between the two media where the light passes through. Light passing from a denser medium to a less dense medium bends away from the normal.
Is it true that matter in medium moves in perpendicular in transverse wave?
Yes. In a transverse wave the direction of particle movement is perpendicular to the direction of the wave.
How much light is reflected and transmitted when light strikes at a perpendicular to a surface?
Only about 4% is reflected, the rest is transmitted. 3. (29.1) When light strikes perpendicular to the surface of a pane of glass, how much light is reflected and how much is transmitted? Normal to the surface refers to a line that is drawn perpendicular to the surface (90°).

Which way will light bend when passiing from air to quartz?
The refractive index of air is about 1.0003, and of quartz about 1.45, so quartz is the more "optically dense" medium in this situation. When light goes from a less dense medium to a more dense medium, it is refracted toward the normal. The normal is the imaginary line perpendicular to the surface where the light enters.
Why light passes undeviated falling straight on a refracting medium?
If by "straight on" you mean at 90 degrees to the surface of the medium, that is because light is only deviated if it makes an angle with the normal, which is an imaginary line perpendicular to the surface of the medium. If no angle is made between the normal line and the light ray, then no refraction occurs and the light passes through in a straight line. For more information see the related link below.
What should be the angle of incidence with respect to the normal of a glass medium so that it does not undergoes refraction?
Radiation that strikes the interface parallel to the normal, i.e. perpendicular to the boundary, is not refracted.
Will light always bend when it changes medium?
Not always. It won't bend if it enters the new medium perpendicular to the surface that separates them, and it won't bend when the refractive indices of the two media are equal.
Does matter in the medium moves perpendicular to a transverse wave?
A wave where the medium moves perpendicular to the direction of the wave is called a transverse wave. Its highest point is called the crest.
How does light travel when the medium it travels through changes and how does light travel when the medium does not change?
Light travels in straight lines when the medium's density is constant. When light enters a different density perpendicularly, it also travels in a straight line. When light enters a higher density at an angle, it bends towards an imaginary line perpendicular to its pont of entry. When light enters a lower density medium, it bends away from the imaginary perpendicular line. This is seen with objects partially submerged in water.

A transverse wave cause its medium to move in what direction?
Perpendicular to the direction the wave travels.

Is it the greater of the wave in a perpendicular medium the greater the wavelength of the wave will be?
yes
