Concave Mirror Converging or Diverging

Draw the ray diagrams to show the formation of image if the lens is i converging and ii diverging. It converges the light so it is also called converging mirror.

The image is 01 meters away the mirror.

. Convex mirrors are also called fish eye or diverging mirrors. The method for drawing ray diagrams for concave mirror is described below. In optics an image is defined as the collection of focus points of light rays coming from an object.

There is a definite relationship between the image characteristics and the location where an object is placed in front of a concave mirror. In this mirror reflecting surface is concave. Convex lens or converging lens and concave lens or diverging lens are the two types of lenses bounded by two spherical surfaces.

A concave mirror of focal length ft can form a magnified erect as well as an inverted image of an object placed in front of it. The method is applied to the task of drawing a ray diagram for an object located beyond the center of curvature C of a concave mirror. For a diverging lens for example a concave lens the focal.

Justify this statement stating the position of the object with respect to the mirror in each case for obtaining these. A concave lens is made by joining two curved surfaces in such a way that it is thinner at the centre. Characteristics of Concave Mirror.

If a bus is located at 5m from this mirror find the position nature and magnification of the image. Calculate the image position and magnification in each case. Convex mirrors are used extensively as part of car mirrors.

Light converges at a point when it strikes and reflects back from the reflecting surface of the concave mirror. A An object is placed 10 cm from a lens of focal length 5 cm. For making simple camera Use of concave lens.

A convex mirror used for rear view on an automobile has a radius of curvature of 3m. Differences between a spherical mirror and a lens. Yet the same method works for.

The magnification produced by a spherical lens and a spherical. Characteristics of Concave Mirrors. Thus it is called a diverging lens.

A concave lens has the ability to diverge a beam of light rays incident on it. In other words it is an image which is located in the plane of convergence for the light. Find the image distance height and magnification.

O In a converging mirror rays coming parallel to the optical axis A. Behind the lens there is a concave mirror of focal length. An object is placed 15cm from a a converging mirror and b a diverging mirror of radius of curvature 20cm.

When the concave mirror is placed very close to the object a magnified erect and virtual image is. As shaving mirrors Use of convex lens. The correct answer is A.

When the inner surface of a spherical mirror is reflected and the outer surface is painted it is called a convex mirror. Diverging light rays from a nearby object. The focal length f of the concave mirror is 4 cm therefore the patients teeth should be less than 4 cm in front of a concave mirror.

If the object is placed 20 cm in front of the mirror then determine the properties of the image. An object of height 3 cm is placed at 25 cm in front of a converging lens of focal length 20 cm. A concave mirror creates an image which is magnified by a factor of 5.

Answer a m-3 b 042. An object 3cm high is held at a distance of 50cm from a diverging mirror of focal length 25cm. Concave mirrors are also called converging mirrors.

As eye-lens in Galilean telescope. Use of concave mirror. C Calculate the image position and magnification in case.

Problems on concave lens. Hence it is also known as a converging mirror. Converging and Diverging mirror Converging mirrors are those that focus light after it has Q.

A 200-m-long uniform beam weighing 880 N rests on walls A and B as shown in the figure Figure 1. Concave mirrors are also known as converging mirrors because they converge light to one prime focus point. Real upright and enlarged.

It should be noted that if the above lenses are surrounded by a material with a refractive. An object is placed 20 cm from a a converging lens and b a diverging lens of focal length 15 cm. Similarly if the reflective surface is curved outwards it is a convex mirror.

A concave mirror has a radius of curvature of 24 cm. WHat is the object distance. The upper part of such a mirror is concave mirror and lower part is a plane mirror.

For a thin lens in air the focal length is the distance from the center of the lens to the principal foci or focal points of the lensFor a converging lens for example a convex lens the focal length is positive and is the distance at which a beam of collimated light will be focused to a single spot. This type of mirror is known as a concave mirror. Its thickness gradually increases as we move towards the edge.

We wish to describe the characteristics of the image for any given object location. Find the nature position and size of the image. A real image is the collection of focus points actually made by convergingdiverging rays while a virtual image is the collection of focus points made by extensions of diverging or converging rays.

Similar to a concave mirror a converging lens produces different image. Lenses The convex lenses are thicker in the middle compared to the edges and are used in converging light rays while the concave lenses are thicker at the edges compared to the middle and are used in diverging. Answer The mirror is convex but the lens is concave.

You can recognize these mirrors easily as the outward bulge is quite. The two common types of lenses are Converging lens or Convex lens Diverging lens or Concave lens. The focal length of a converging lens is always positive while the focal length of a diverging lens is always negative.

The characteristics of a concave mirror and concave mirror image are given below. An object of 2 cm height is placed at a distance of 10 cm from a concave mirror of radius of curvature 30 cm. The purpose of this lesson is to summarize these object-image relationships - to practice the LOST art of image description.
