its an angle
An angle.
A virtual image is formed when light rays appear to meet at a point, but do not actually converge at that point. This type of image is formed in locations where the rays are not physically intersecting.
An image that is formed when light rays meet is called a real image. This type of image is formed when light rays converge to a point either on a screen or a surface.
angle
A triangle.
an angle
A figure formed by two rays with the same endpoint is called an angle. The point where the two rays meet is known as the vertex of the angle, while the rays themselves are referred to as the sides. Angles can be measured in degrees or radians and are classified based on their measures, such as acute, right, obtuse, or straight.
An image is formed where light rays meet at the focal point of a converging lens or mirror. This image can be real or virtual, depending on the position of the object relative to the focal point.
The image formed when light rays actually meet is called a real image. This type of image can be projected onto a screen and is formed when the rays of light actually converge at a point.
A virtual image is formed where the light rays diverge and appear to meet at a point behind the mirror or lens. This point is known as the virtual focus. It cannot be projected onto a screen, as it does not actually exist at that point.
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.
The point where light rays meet is called the focal point.
