What is the focal length of concave mirror?
Focal Length – The distance between the pole P of the concave mirror and the focus F is the focal length of the concave mirror. Thus, the focal length of a concave mirror can be estimated by obtaining a ‘Real image’ of a distant object at its focus, as shown in the figure.Click to see…
Focal Length – The distance between the pole P of the concave mirror and the focus F is the focal length of the concave mirror. Thus, the focal length of a concave mirror can be estimated by obtaining a ‘Real image’ of a distant object at its focus, as shown in the figure.Click to see full answer. Likewise, people ask, is the focal length of a concave mirror positive or negative?f, the focal length, is positive for a concave mirror, and negative for a convex mirror. When the image distance is positive, the image is on the same side of the mirror as the object, and it is real and inverted. When the image distance is negative, the image is behind the mirror, so the image is virtual and upright.Also, what is the focal length of concave mirror and convex lens? 3. Since, the image formed by the lens is real so it can also be obtained on a screen as that of concave mirror. As, the focal length of a convex lens is equal to the distance between optical centre and any of its focus. So, focal length can be estimated by obtaining a real image of a distant object at its focus. Secondly, what is the focal length of a convex mirror? A convex mirror has a focal length of -10.8 cm. An object is placed 32.7 cm from the mirror’s surface.What is the focal length of this mirror? Answer and Explanation: The focal length of a plane mirror is infinite. When parallel rays fall on a mirror surface, they are brought to a point after reflection. This point is called the focal point and the distance of this point from the center of the mirror is called the focal length of the mirror.
