Which point is the image of (-7 1) reflected across the y-axis?
To find the image of the point (-7, 1) reflected across the y-axis, you need to change the sign of the x-coordinate while keeping the y-coordinate the same. Therefore, the x-coordinate of -7 becomes 7, resulting in the reflected point being (7, 1).
What happens to a coordinate reflected across y equals x?
The x and y coordinates swap places. Thus, the point (a,b) becomes (b, a).
When is the image said to be real or virtual image?
An image is called real if the light rays coming from a point(point on object) meet at a point after reflection or refraction. An image is virtual if the light rays do not actually meet after reflection or refraction. These rays appear to come from a point which is the point where we say virtual image is formed.
How are the coordinates of a pre-image affected by a translation?
When a pre-image undergoes a translation, each coordinate of the pre-image is adjusted by adding a fixed value, known as the translation vector. This means that every point of the pre-image moves the same distance and direction, resulting in a new set of coordinates for the image. The relative positions of the points remain unchanged, preserving the shape and size of the figure. For example, if a point (x, y) is translated by (a, b), its new coordinates will be (x + a, y + b).
How do the coordinates of a point change when it is reflected over the y-axis?

The point T(-3-6) is reflected over the line y -x. What are the coordinates of the resulting point T and acirc and 128 and sup2?
The image is at (6, 3).
What is the difference between object distance and image distance?
image distance is the distance from the point of incidence on the mirror, the where the image is reflected to.object distance is the distance from the actual object being reflected to the point of incidence on the mirror where it's reflected as an image.
What does reversed mean in reflections?
In reflections, "reversed" means that the image appears flipped from left to right compared to the original object. Each point on the object is reflected across the mirror line to create the reversed image.
Why is the reflected image in a polished spoon is inverted and reduced?
The reflected image in a polished spoon is inverted because light rays reflect off the curved surface of the spoon, causing them to cross over each other. The reduction in size occurs because the curved surface acts like a concave mirror, which converges the reflected light rays towards a focal point, resulting in a smaller image being formed.
How does light reflect of a convex mirror?
Light rays striking a convex mirror are reflected away from each other due to the outward curve of the mirror. The reflected rays diverge and do not converge to a focal point, resulting in an upright and diminished virtual image.
If the point (2,-5) is reflected in the line y=x, then the image is what?
(-5.2)
How does a lateral inversion happens in a concave mirror?
Lateral inversion in a concave mirror occurs because light rays are reflected in such a way that causes the image to be laterally reversed. This happens when rays from a point on the object converge at a point on the other side of the mirror, resulting in the inversion of the image from left to right.
What creates an image that is reflected through a focal point?
An image that is reflected through a focal point is created by parallel light rays that hit the concave mirror and reflect towards the focal point due to the mirror's curvature. This creates a real, inverted image at the focal point.
What is the only location where concave mirror will not produce an image?
At the focal point of the mirror, a concave mirror will not produce a real image. This is because at the focal point, the reflected rays are parallel and do not converge to form a real image.
When the point 2-5 is reflected in the x-axis what are the coordinates of its image?
(2,-5) turns into 2,5
