Question 3: What is the difference between concave and convex mirrors in terms of physical appearance?Īnswer: A concave mirror is formed by painting the outside surface of a spherical mirror, whereas a convex mirror is formed by painting the interior surface of a spherical mirror. Question 2: Which mirror is used in headlights, searchlights and projectors?Īnswer 2: Concave mirrors are used in headlights, searchlights and projectors as they give a magnified image of the objects. Question 1: What is the difference between concave and convex mirrors in terms of type?Īnswer 1: Convex mirrors are diverging mirrors whereas concave mirrors are converging mirrors.
#CURVED PHOTO REFLECTOR INSTALL#
For instance, they are the ones store owners install in their shops that are large disk-like reflective surfaces. It also serves as a good security device. Thus, because of its wider fields of view compared to other reflective surfaces, we use them mostly in automobile side mirrors. Thus, when a beam of light is directed on it, it will make the initially parallel rays, making up the beam, diverge after striking its reflective surface. These are called diverging mirrors because it makes rays diverge upon reflection. Dentists also use these types of mirrors.
Further, a smaller image forms when the object is farther away from the mirror, i.e. A large image forms when the object is closer to the mirror, i.e. Moreover, it may reflect an image in two ways. When the light bounces by the curve up to a specific area, it creates an image. It is important to note that the reflecting surface of a concave mirror bends inward to focus, explicitly, away from the light source. We use them as reflectors in projectors, searchlights, shaving mirrors and more We use them as rearview mirrors in cars and bikes Images project on screen because they are real Images do not project on the screen because they are virtual It’s a mirror that has a reflecting surface away from the centre of curvatureĪ concave mirror is one that has a reflecting surface towards the curvature’s centre Difference between Concave And Convex Mirrorĭifference between Concave And Convex Mirror Basis of Comparison Moreover, the image which forms is erect, diminished and concerns the object. It will create a virtual image after it reflects from the mirror, the ray of lights will meet at an exact point. You can call it a kind of spherical mirror in which the reflective surface curves outwards. As a result, the light rays do not intersect on the mirror’s object side and create the virtual image of the real object. In these, the incident ray which emerges from the same point reflects off and moves in a different direction. Definition of Convex MirrorĬonvex mirrors are diverging mirrors. Thus, the image which forms may be large or small, real or virtual. However, when there is an increase in the distance between the object and the mirror, the size of the image will reduce thereby creating a real image. When we place this mirror too close to an object, we get a magnified and virtual image. A concave mirror’s shape is similar to a spoon. The parallel incident rays fall on the mirror’s surface and the rays reflect and meet at a certain point known as the focal point.
