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. Draw a normal line on the second sheet from the mirror.4 FAQs about Concave And Convex Mirror Definition of Concave MirrorĬoncave mirrors are converging mirrors. Take another sheet and place it on the table in contact with the vertical mirror. Make sure that the light in the room is not bright. Take a paper sheet and make a small hole in its center. The angle of incidence, and the angle of reflection, are equal to each other. The incident ray, the normal at the point of incidence and reflected ray, all lie in the same plane. Describe an activity to show that incident ray, reflected ray and the normal, at the point of incidence, all lie in same plane. (d) the shiny outer surface of the bicycle bell.ġ. State the type of mirror that the following items/objects would correspond to: The size of the image decreases when we move object away from the mirror.ħ.The size of the image increases when we move object towards the mirror.Image is virtual, erect and diminished.
Also mention the basic characteristics of the image formed by this type of mirrors.Ĭharacteristics of the image formed by this mirror are as following – Name the type of mirror that Rohit must have suggested to his father. Rohit suggested to his father to fix a ‘security mirror’ which would provide them with a wider view of the surrounding of their shop. Draw a ray diagram to show the formation of an image when the object is placed between the C and F points of a concave mirror.Īnswer: (a) Virtual image (b) Concave mirrorĦ. (3) Nature of the image does not change in both the cases.ģ. (2) The size of the image decreases when an object moves away from the mirror. (1) The size of the image increases when an object moves towards the mirror. How does changing the distance of the object, from a convex mirror, affect the size and nature of the image formed by it? It is always erect with respect to object.Įxample of a virtual image is image of our face formed by plane mirror is virtual.Ģ.It is formed by the apparent intersection of light rays.It always forms in front of the mirror.It is formed by actual intersection of light rays.Explain clearly the difference between a real image and a virtual image. Answer the following questions in brief.ġ.
