For it to glide through the air.
Otherwise the image formed will be blurred and mostly distorted. That is why we expect the surface of the mirror to be optically plane. Hence smooth.
No. It is not a plane surface like that of a plane mirror because a plane mirror is straight and it does not have any curve in it. the sculpture's surface is like that of a Convex Mirror
The surfaces used as the measure of lowest friction are generally wet ice on wet ice. Some materials, such as superfluid Helium III have no measurable friction.
Regular reflection means the incident rays parallel to each other fall on plane or smooth surface and reflects back equal to the angle of incidence is called regular reflection.
Plane surface with negligible friction.
inclined plane
Otherwise the image formed will be blurred and mostly distorted. That is why we expect the surface of the mirror to be optically plane. Hence smooth.
Smooth
Yes, "plane" is a noun; a word for a type of aircraft; a tool used to smooth the surface of wood; a flat surface; a level of development or existence; a word for a thing .The word "plane" is also a verb and an adjective.
An inclined plane is a hard, smooth, inflexible surface. An inclined plane is a simple machine, an example of which would be a ramp.
The noun "plane" is a singular, common, concrete noun; a word for a type of aircraft; a tool used to smooth the surface of wood; a flat surface; a level of development or existence; a word for a thing .The word "plane" is also a verb and an adjective.
Any tree of the genus Platanus., Without elevations or depressions; even; level; flat; lying in, or constituting, a plane; as, a plane surface., A surface, real or imaginary, in which, if any two points are taken, the straight line which joins them lies wholly in that surface; or a surface, any section of which by a like surface is a straight line; a surface without curvature., An ideal surface, conceived as coinciding with, or containing, some designated astronomical line, circle, or other curve; as, the plane of an orbit; the plane of the ecliptic, or of the equator., A block or plate having a perfectly flat surface, used as a standard of flatness; a surface plate., A tool for smoothing boards or other surfaces of wood, for forming moldings, etc. It consists of a smooth-soled stock, usually of wood, from the under side or face of which projects slightly the steel cutting edge of a chisel, called the iron, which inclines backward, with an apperture in front for the escape of shavings; as, the jack plane; the smoothing plane; the molding plane, etc., To make smooth; to level; to pare off the inequalities of the surface of, as of a board or other piece of wood, by the use of a plane; as, to plane a plank., To efface or remove., Figuratively, to make plain or smooth.
A smoothing plane is used to level or smooth rough wooden surfaces. Function is variable; however, it was designed to be used with wood. It can be used, for example, to smooth and level a rough-cut surface; or to consistently remove thicknesses from the exterior of a piece of wood. It is much more efficient than beginning to smooth a surface with extra-coarse sandpaper.
The exterior part of anything that has length and breadth; one of the limits that bound a solid, esp. the upper face; superficies; the outside; as, the surface of the earth; the surface of a diamond; the surface of the body., Hence, outward or external appearance., A magnitude that has length and breadth without thickness; superficies; as, a plane surface; a spherical surface., That part of the side which is terminated by the flank prolonged, and the angle of the nearest bastion., To give a surface to; especially, to cause to have a smooth or plain surface; to make smooth or plain., To work over the surface or soil of, as ground, in hunting for gold.
a plane; a study of geometry is called "plane" geometry.
"Airplane" would be "avión". "Cepillo" is the tool used to shave surfaces. "Plano" is a smooth even surface.
Yes, the noun 'plane' is a common noun; a general word for a type of aircraft; a general word for a tool used to smooth the surface of wood; a general word for a flat surface; a general word for a level of development or existence.The word "plane" is also a verb and an adjective.
