how can we say that the image formed by a concave mirror is always real if object is virtual?
please help
please help
A real image in a concave mirror is an image that is formed by the actual intersection of light rays. It is a projection of an object that can be captured on a screen or surface, and it is always inverted compared to the object.
A real image is formed in a concave mirror when light rays from an object converge after reflecting off the curved surface of the mirror. This convergence causes the image to appear on the same side of the mirror as the object, and it can be captured by a screen or surface placed at the focal point of the mirror.
A real image is formed by the actual intersection of light rays and can be captured by a screen, while a virtual image is formed by the extension of light rays and cannot be captured. A real image is always inverted, while a virtual image can be either upright or inverted.
Yes, a real image can be magnified in a concave mirror by placing the object closer to the mirror than the focal point. This causes the image to be larger than the object and can be further magnified by moving the screen closer to the mirror.
Real images in concave mirrors have several real-life applications, including use in telescopes, microscopes, and camera lenses. They are also used in medical imaging technologies such as MRI and X-ray machines.
