Concave Mirror Converging or Diverging

Differences between a spherical mirror and a lens. For making simple camera Use of concave lens.

It should be noted that if the above lenses are surrounded by a material with a refractive.

. The plus sign indicates that the focal point is real or the rays pass through the point. Convex mirror another name for a concave mirror 3. Characteristics of Concave Mirror.

In optics an image is defined as the collection of focus points of light rays coming from an object. The correct answer is A. A concave lens is made by joining two curved surfaces in such a way that it is thinner at the centre.

When the inner surface of a spherical mirror is reflected and the outer surface is painted it is called a convex mirror. Common terms for Spherical mirrors. There is a definite relationship between the image characteristics and the location where an object is placed in front of a concave mirror.

Its thickness gradually increases as we move towards the edge. Properties of Convex mirror Reflecting surface is curved outwards. Convex lens or converging lens and concave lens or diverging lens are the two types of lenses bounded by two spherical surfaces.

Real upright and enlarged. 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. The purpose of this lesson is to summarize these object-image relationships - to practice the LOST art of image description.

This type of mirror is known as a concave mirror. Characteristics of Concave Mirrors. We wish to describe the characteristics of the image for any given object location.

An object is placed 15cm from a a converging mirror and b a diverging mirror of radius of curvature 20cm. The two common types of lenses are Converging lens or Convex lens Diverging lens or Concave lens. Use of concave mirror.

As eye-lens in Galilean telescope. In this mirror reflecting surface is concave. Answer The mirror is convex but the lens is concave.

You can recognize these mirrors easily as the outward bulge is quite. 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. An object 3cm high is held at a distance of 50cm from a diverging mirror of focal length 25cm.

The characteristics of a concave mirror and concave mirror image are given below. 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. An object of 2 cm height is placed at a distance of 10 cm from a concave mirror of radius of curvature 30 cm.

Similarly if the reflective surface is curved outwards it is a convex mirror. Image the point at which rays of light converge 5. The incident and reflected rays follow the laws of reflection at the point of incidence point P.

Problems on concave lens. As shaving mirrors Use of convex lens. An object is placed 20 cm from a a converging lens and b a diverging lens of focal length 15 cm.

The focal length f 15 cm. Thus it is called a diverging lens. Concave mirrors are also called converging mirrors.

In other words it is an image which is located in the plane of convergence for the light. Answer a m-3 b 042. Justify this statement stating the position of the object with respect to the mirror in each case for obtaining these.

Find the nature position and size of the image. Concave mirrors are also known as converging mirrors because they converge light to one prime focus point. Pole of the mirror on the concave mirror or a convex mirror is reflected obliquely.

Find the image distance height and magnification. A An object is placed 10 cm from a lens of focal length 5 cm. Draw the ray diagrams to show the formation of image if the lens is i converging and ii diverging.

A concave lens has the ability to diverge a beam of light rays incident on it. A concave mirror is used to concentrate sunlight in order to generate heat in a solar furnace. Light converges at a point when it strikes and reflects back from the reflecting surface of the concave mirror.

Converging mirror a visual reproduction of an actual object 2. If the object is placed 20 cm in front of the mirror then determine the properties of the image. Convex mirrors are used extensively as part of car mirrors.

Focal point a diverging mirror that always produces a virtual image 4. The upper part of such a mirror is concave mirror and lower part is a plane mirror. 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.

It converges the light so it is also called converging mirror. A convex mirror used for rear view on an automobile has a radius of curvature of 3m. Determine the image distance the magnification of the image the image height and the properties o f the image.

A concave mirror has a radius of curvature of 24 cm. Principal axis a ray that follows the path of the radius of a spherical mirror. Converging mirror.

Convex mirrors are also called fish eye or diverging mirrors. A concave lens is a diverging lens that helps people view objects at large distances if they are dealing with Myopia. The magnification produced by a spherical lens and a spherical.

However for people dealing with hypermetropia a converging lens convex lens is used which we will discuss in this article. Calculate the image position and magnification in each case. When the concave mirror is placed very close to the object a magnified erect and virtual image is.

A 10-cm high object is placed 30 cm from a 15-cm focal length converging lens. C Calculate the image position and magnification in case. If a bus is located at 5m from this mirror find the position nature and magnification of the image.

Hence it is also known as a converging mirror.
