while convex mirror forms diminished image, the concave mirror either forms an enlarged image or a diminished one, depending upon the position of the object. A concave amkeup mirror is designed so that a person 28.7 cm in front of it sees an upright image ata distance of 51.1 cm behind the mirror. From the calculations in this problem it can be concluded that if a 4.00-cm tall object is placed 45.7 cm from a concave mirror having a focal length of 15.2 cm, then the image will be inverted, 1.99-cm tall and located 22.8 cm from the mirror. sign conventions . Look at the given picture below. Problem 19. concave and convex mirrors . Problem 8. So imagine our eye, again, is over here, looking at this object inside of the mirror, and we're gonna see an image of the object. What is the radius of curvature of the mirror? The image in the convex mirror is always a virtual image, standing like an object, and looks smaller than the real thing. Ray, coming from first mirror turns back with same path after reflecting from second mirror. Note: What is the radius of curvature formula? Clicker problem • In order for a real object to create a real, inverted enlarged image, a) we must use a concave mirror. Numerical Problems: Note: For mirror u R f m v Virtual Image Real Image Virtual Image Real Image Concave mirror-ve-ve-ve +ve-ve +ve-ve Convex mirror-ve +ve +ve +ve----+ve----Object distance is –ve for both the mirrors. Problem Solving . principle axis and radius of curvature . The main difference between a convex and concave mirror lies in the image formed by the two mirrors, i.e. It is used in car rearview mirrors and surveillance mirrors because it can be seen in a wide range. lots of examples . Answer in cm. On the contrary, in a concave mirror, the reflecting surface bulges inwards.. The results of this calculation … The image formed by a concave mirror can be projected on a screen. Find focal points of mirror 2 in terms of d. Ray hits the vertex of mirror 1 and reflects with same angle. Key Differences between Convex Mirror and Concave Mirror. Whenever a light ray hits the interface between two … b) we must use a convex mirror. The results of this calculation agree with the principles discussed earlier in this lesson. This mirror, this time instead of concave, this is a convex mirror. Real image and virtual image of concave mirror. ray tracing for mirrors (PowerPoint) ⇒ the thin-lens / mirror equation and the magnification equation . From the calculations in this problem it can be concluded that if a 4.0-cm tall object is placed 35.5 cm from a convex mirror having a focal length of -12.2 cm, then the image will be upright, 1.02-cm tall and located 9.08 cm behind the mirror. Use the mirror formula to show that a)an object placed between f and 2f of a concave mirror produces a real image beyond 2f b)a convex mirror always produces a virtual image independent of the location of the object c)an object placed between the pole and focus of a concave mirror … c) neither a concave nor a convex mirror … Two concave mirrors are placed on same principal axis. We're gonna see the object right here, but we're also gonna see the image of the object. Optics Exam2 and Problem Solutions 1. Let's say we used a mirror shaped like this. Concave mirrors used in torch lights and reflecting telescopes etc. Example.
