images 2. In a convex mirror, the virtual image formed is always diminished, whereas in a concave mirror when the object is placed between the focus and the pole, an enlarged virtual image is formed. Give one use each of a concave and a convex mirror. images formed [2011, 2016, 2017] ... [1M] (a) Towards the screen (b) Away from the screen (c) Very far away from the screen (d) Behind the screen on Light Class 10 The size of the image formed by the convex mirror is always smaller than that of the object. MCQ Questions for Class 10 Science Chapter 10 Light ... Compound Microscope - Types, Parts, Diagram, Functions Types Of Images. An incident ray which is parallel to the principal axis is reflected as if it came … The mirror required for this purpose is : … When an object is placed at infinity, a virtual image is formed at the focus. A virtual image has the following properties: 1. A convex mirror enables the driver to view such larger area of the traffic behind him. A convex mirror enables the driver to view such larger area of the traffic behind him. Convex Mirror Concave mirror forms a sharp image, whereas a convex mirror cannot form a sharp image of the distant object. Formation of images by a convex mirror Concave Mirrors And Convex Mirrors Assertion (A): For observing traffic at back, the driver mirror is convex mirror. A convex mirror or diverging mirror is a curved mirror in which the reflective surface bulges towards the light source. SOLUTION: The image formed in a convex mirror is always virtual and erect, whatever be the position of the object. convex mirror i) Concave mirror:-is a spherical mirror whose reflecting surface is curved inwards. 2. To determine the focal length of a concave mirror, a student focuses a classroom window, a distant tree and the Sun on the screen with the help of a concave mirror. Convex mirror; Concave mirror: It is that in which the reflection occurs through inner surface of mirror. Concave mirror, 2. The first is graphical, and the second analytical. A convex mirror always forms a virtual, erect and diminished image. An optical instrument consists of two convex lenses of short focal lengths primarily used for observing a highly magnified image of minute objects. In this section, let us look at the types of images formed by a convex mirror. Properties of an image formed by a convex mirror: The image is always formed behind the mirror, between the pole and its focus. A concave mirror will only produce an upright … When the reflection of an object is seen in a flat mirror? b. always be virtual. [Note : The exercise helps you deduce algebraically properties of … A virtual image is produced when the light rays from a source don’t cross or meet at a point to form an image. C) virtual, inverted and diminished. i) Concave mirror:-is a spherical mirror whose reflecting surface is curved inwards. E) erect, virtual and magnified A convex mirror is a type of spherical mirror in which the reflecting surface is the bulged out portion of the sphere. Use the mirror equation to deduce that : c) the virtual image produced by a convex mirror is always diminished in size and is located between the focus and the pole. Images formed by a convex mirror are always Options. Hence, it is also called a diverging mirror. Location of the image is always between the focal point and vertex of the mirror. 25% 25% 25% 25% 1 21 41 2 22 42 3 23 43 4 24 44 5 25 45 6 26 46 7 27 47 8 28 48 9 29 49 10 30 50 11 31 12 32 1 13 33 14 34 2 15 35 16 36 3 17 37 18 38 19 4 39 20 40 When an object is placed at a finite distance from the mirror, a virtual image is formed between the pole and focus of the convex mirror. IN CASE OF CONVEX MIRROR: A convex mirror always forms a virtual and erect image. A convex mirror forms a virtual, diminished and upright image of an object. A convex mirror can only form 2 types of images when the object is placed at different positions. Convex mirror; Concave mirror: It is that in which the reflection occurs through inner surface of mirror. But a virtual image of an object is always formed in a convex mirror. A virtual image is always erect. Page Number: 171. A case 1 image is formed when d o > f and f is positive, as in Figure 10a. The image produced by a convex mirror is always virtual, and located behind the mirror. Convex mirror, 3. Convex mirror: It is that in which the reflection occurs through outer surface of mirror. Rear mirrors used in vehicles are convex mirrors. Which image will be formed when an object is placed between the focal length and the convex mirror? An image is formed when the reflected rays actually meet or appear to meet at a … Rays of light parallel to the principal axis after reflection from a concave mirror meet at a point (converge) on the principal axis. Now, let’s study the types of images formed by a convex mirror. b. always be virtual. 2) The image produced by a convex mirror is always closer to the mirror than it would be in a plane mirror for the same object distance. SHOW ANSWER. Answer: Concave mirrors are used in the headlight of cars and scooters. An optical instrument consists of two convex lenses of short focal lengths primarily used for observing a highly magnified image of minute objects. C) erect, virtual and diminished. A convex lens of small focal length and its primary use is to see the magnified image of small objects. Rays from Sun converge at a point 15 cm in front of a concave mirror. 10. Convex mirror always forms a virtual image and a smaller image. Thick in the middle and thin at the edge Thin in the middle and thick at the edge. The image formed by the convex mirror is always virtual and erect. Question 2: To determine the focal length of a convex lens, a student focusses a classroom window, a … 1) A concave mirror always forms an enlarged real image of a real object. (IV) Images formed by convex mirrors are usually larger than the object. 3) Concave- curves inwards. The image formed in a convex mirror is always erect, virtual and diminished in size. – Real Image – Virtual Image Dec 03,2021 - The size of the image formed by the convex mirror isa)Always smaller than the size of the objectb)Same as the size of the objectc)Depends on the position of the objectd)Always greater than the size of the objectCorrect answer is option 'A'. C) could be real or virtual; it depends on whether the object distance is smaller or greater than the focal length. This implies, the image distance is always positive in case of convex mirror and the image is always formed on the other side of the object i.e., behind the convex mirror. They are concave mirror and convex mirror. This image, formed by light rays leaving the flat refractive surface, is Select one: a. real and closer to the viewer than the object. Concave parabolic (b) Differences between a real and virtual image : Real Image Virtual Image It can be taken on a screen It can not be taken on a screen It is always inverted It is always erected When reflected or refracted rays actually meet at a point, then real image is formed. object, then the mirror is (a) concave (b) convex 25% 25% 25% 25% 1 21 41 2 22 42 3 23 43 4 24 44 5 25 45 6 26 46 7 27 47 8 28 48 9 29 49 10 30 50 11 31 12 32 1 13 33 14 34 2 15 35 16 36 3 17 37 18 38 19 4 39 20 40 In which direction should he move the lens to focus a distant tree instead of the grill? 10 question is disucussed on EduRev Study Group by 218 Class 10 Science /a.
