Is U Positive In Convex Lens? According to Cartesian sign convention, object distances (u) are always negative as the object is placed to the left of the mirror/lens. Focal length (f) is positive for a convex lens and convex mirror. Focal length is negative for concave lens and concave mirror. Is f positive for convex
Is Your Image Exactly The Same In Size As You Are Where Is It Apparently Found? Answer Expert Verified Your image will be the same size as you are if your looking for the image produced by plane mirror. In plane mirror, the light rays striking on it have angle of incidence is equal to

What Do You Mean By Real And Virtual Image? In optics, an image is defined as the collection of focus points of light rays coming from an object. A real image is the collection of focus points actually made by converging rays, while a virtual image is the collection of focus points made by extensions
What Happens When A Ray Passes Through Principal Axis? Any incident ray traveling parallel to the principal axis of a converging lens What happens to the light ray which travel along the principal axis? One ray of light becomes parallel to the principal axis of the lens and thus, passes through another focus after refraction
What Is A Mirror Used For In Dentistry? A concave mirror gives the dentist a magnified reflection of the mouth while also refracting a bit of light. This means the image in the mirror is larger, brighter, and, for the dentist, easier to see. Another plus of using a concave mirror is that the image
What Is The Difference Between Concave And Convex Mirror? A convex mirror is curved outwards, and concave mirror is curved inwards. (B). The focal point is in front of the convex mirror, and for a concave mirror, it is behind. … The fundamental difference between them is that the reflective surface of a concave mirror
Which Types Of Mirror Do We Use In Our Daily Life? Concave mirrors are used in torches to give a powerful beam of light. Also, Concave mirrors are used by dentist to observe the patient’s teeth. Convex mirror is used in side-mirrors of cars. Plane mirrors are used in the normal mirror that we use
