Because a reflection reverses the direction of the component of the wave vector of the light hitting the reflecting surface which is orthogonal to the surface. The component parallel to the surface will not change.
This means the light going towards a mirror, will go away from the mirror after reflection. But if it went from the left to the right, it will continue to go from the left to the right. Same with up and down.
In three dimensions this is the same as changing the handedness of the image.

What is a similar plane figure?
It is a figure that is the same as another figure in the plane. A square is the same plane figure as another square, but a cube is same the same plane figure even tho it is made up of 6 squares.
Which plane figure has 8 sides?
An 8-sided plane figure is an octagon.
Which transformation is a flipping of a plane about a fixed line?
Reflection in the line.
Is a quadrilateral any plane figure with four straight sides?
A quadrilateral is a closed plane figure with four straight sides.
What shape has a closed plane figure with at least three sides?
A three sided closed plane figure (shape) is a triangle.
What rigid motion does not preserve orientation?
A rigid motion that does not preserve orientation is a reflection. In a reflection, points are flipped over a line (in two dimensions) or a plane (in three dimensions), resulting in a change in the order of points and their orientation. For example, if you reflect a shape across a line, the left and right sides of the shape will switch places, reversing its orientation. This contrasts with motions like translations and rotations, which maintain the original orientation of the figure.
What changes the position or orientation of a figure on a coordinate plane?
This is a transformation which could be a rotation, translation or reflection.
What does a line reflection not preserve?
A reflection in a line l is a correspondence that pairs each point in the plane and not on the linewith point P' such that l is the perpendicular bisector of segment PP'. IF P is on l then P is paired with itself ... Under a reflection the image is laterally inverted. Thus reflection does NOT preserve orientation...
What type of rotation will preserve the orientation of a h-shaped figure in the gird?
Rotation, in the plane of the grid, through 180 degrees.
How does a reflection affect the properties of two-dimensional figures?
A reflection in two-dimensional figures creates a mirror image across a designated line, known as the line of reflection. This transformation preserves the shape and size of the figure, meaning that properties such as angles, lengths, and area remain unchanged. However, the orientation of the figure is reversed, which can affect how it interacts with other shapes or coordinates in a plane. Overall, a reflection maintains congruence while altering the figure's position and orientation.
When a figure translates to the right or translates up on the coordinates plane?
reflection
What happens when you perform a translation of a figure?
It is moved across the plane. Its size or orientation are not changed.
Where the image has the opposite orientation as the preimage?
The image has the opposite orientation as the preimage when a transformation, such as a reflection, is applied. In this case, the resulting shape or figure is flipped across a line or plane, reversing the order of points and altering the direction of any associated angles. This change in orientation can be observed in geometric transformations, where, for example, a clockwise arrangement of points in the preimage may become counterclockwise in the image.
What is the intersection of a plane with a solid figure?
The intersection of a plane with a solid figure is the set of points where the plane cuts through the solid. This intersection can take various forms depending on the orientation and position of the plane relative to the solid; it can be a point, a line, or a two-dimensional shape (such as a circle or polygon). The specific nature of the intersection is determined by the geometry of both the plane and the solid figure involved.
A what of the plane is a transformation which shifts all the points in a plane figure without altering the shape of the figure?
A transformation that shifts all the points in a plane figure without altering the shape of the figure is called a "translation." During a translation, each point of the figure moves the same distance in a specified direction, resulting in a congruent figure in a new position. This operation maintains the figure's size, shape, and orientation.
What does transformation mean in geometry?
A transformation is moving or changing the shape of a figure on the Cartesian plane by a translation, by a reflection, by a rotation or by an enlargment
A figure is transformed in the plane such that no point maps to itself. What type of transformation?
It could be a reflection with the mirror line outside the figure; it could be a rotation with the centre of rotation outside the figure; or it could be a translation.
