Why must electric field line be perpendicular to equipotential surfaces?
If the field lines were not perpendicular to the surface, then they could be decomposed into components perpendicular and parallel to the surface. But if there is an E-field along the surface, the surface is no longer an equipotential.
A line is perpendicular to another line when?
A line is perpendicular to another line when it is at an angle of 90° to the other line. + (that plus sign is an example of a perpendicular line)
When is a line perpendicular to a plane?
A line is perpendicular to a plane when it is perpendicular on two lines from the plane
What is the difference between a perpendicular line and a perpendicular bisector?
A perpendicular line is one that is at right angle to another - usually to a horizontal line. A perpendicular bisector is a line which is perpendicular to the line segment joining two identified points and which divides that segment in two.
How do you relate parallel and perpendicular lines to the real world?
If you are sitting in a room, the ceiling and the floor are parallel to each other. The walls are perpendicular to the floor and to the ceiling. So any line on these surfaces will be parallel to or perpendicular to any line on the other surface. And if they were not, the building could be quite unstable.
What is a line perpendicular to a surface called?
The line perpendicular to a surface at a point is called the normal
What is the angle of incidence of mirrors?
The angle of incidence of mirrors is the angle between the incident ray (incoming light ray) and the normal (perpendicular line) to the surface of the mirror at the point where the ray strikes the mirror.
What is the name of the line drawn perpendicular to the surface where light ray strikes?
A normal line is the name of the line drawn perpendicular to the surface where a light ray strikes.
What is the line perpendicular surface at the point is incidence?
The line perpendicular to a surface at the point of incidence is known as the normal line. It represents the direction that is perpendicular to the surface at that specific point. This normal line is used in optics to determine the angle of incidence and reflection for light rays interacting with the surface.
A line perpendicular to a surface?
Would be at at 90 degrees to the surface, in other words at right angles. So a line which was perpendicular to a horizontal surface would be vertical.
What is the name of the line drawn perpendicular to the surface where a light ray strike?
A normal line is the name of the line drawn perpendicular to the surface where a light ray strikes.
What is the name of the line drawn perpendicular to the surface where light rays strike?
A normal line is the name of the line drawn perpendicular to the surface where a light ray strikes.
The angle of incidence is the angle between the incident ray and the line to the surface?
Line perpendicular to the surface.
What is a line perpendicular to a reflecting surface called?
a tangent
Why must electric field line be perpendicular to equipotential surfaces?
If the field lines were not perpendicular to the surface, then they could be decomposed into components perpendicular and parallel to the surface. But if there is an E-field along the surface, the surface is no longer an equipotential.
What is the line perpendicular to a reflecting surface where the incident ray ends and the reflected ray begins called?
The line perpendicular to a reflecting surface where the incident ray ends and the reflected ray begins is called the normal line.
What is the 'normal' to a surface?
The normal to a surface is an imaginary line that is perpendicular to the surface at a specific point. It indicates the direction that is perpendicular to the surface and is used in geometry and physics to determine angles of incidence and reflection.
