Key Differences between Convex Mirror and Concave Mirror. Problem 19. b) we must use a convex mirror. lots of examples . principle axis and radius of curvature . The image in the convex mirror is always a virtual image, standing like an object, and looks smaller than the real thing. Two concave mirrors are placed on same principal axis. 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. 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. What is the radius of curvature of the mirror? The results of this calculation agree with the principles discussed earlier in this lesson. The image formed by a concave mirror can be projected on a screen. 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 … We're gonna see the object right here, but we're also gonna see the image of the object. Real image and virtual image of concave mirror. Let's say we used a mirror shaped like this. Concave mirrors used in torch lights and reflecting telescopes etc. Whenever a light ray hits the interface between two … Problem 8. Optics Exam2 and Problem Solutions 1. 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. It is used in car rearview mirrors and surveillance mirrors because it can be seen in a wide range. On the contrary, in a concave mirror, the reflecting surface bulges inwards.. Problem Solving . This mirror, this time instead of concave, this is a convex mirror. Ray, coming from first mirror turns back with same path after reflecting from second mirror. Look at the given picture below. The results of this calculation … c) neither a concave nor a convex mirror … Clicker problem • In order for a real object to create a real, inverted enlarged image, a) we must use a concave mirror. Answer in cm. 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. ray tracing for mirrors (PowerPoint) ⇒ the thin-lens / mirror equation and the magnification equation . concave and convex mirrors . sign conventions . 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. Example. Note: What is the radius of curvature formula? The main difference between a convex and concave mirror lies in the image formed by the two mirrors, i.e. Find focal points of mirror 2 in terms of d. Ray hits the vertex of mirror 1 and reflects with same angle.
