## Difference Between Convex and Concave Lens (with Figure, Example and Comparison Chart)

Conclusion So, with the above examples and figures, you might have got a clear understanding of the difference between the two types of lenses. If the answer is not available please wait for a while and a community member will probably answer this soon. A six-foot tall person would have an image that is larger than six feet tall; the magnification is greater than 1. The reflecting surface of a concave mirror bent inward to focus, i. For parallel rays, such as those coming from a very distant object, a can do a better job.

## Concave and Convex Mirrors

Convex mirror is also known as diverging mirror as this mirror diverges light when they strike on its reflecting surface. The object in the image formed by the convex mirror look smaller than the original size of the object. The correct combination of mirrors is: a plane, convex and concave mirror b concave, plane, convex mirror c plane, concave and convex mirror d convex, concave and plane mirror. For such simplified situations, the image is a vertical line with the lower extremity located upon the principal axis. Ray diagrams have been a valuable tool for determining the path taken by light from the object to the mirror to our eyes.

## Image Characteristics for Concave Mirrors

Answer: d Explanation: Convex lens converges all the rays and the distance between lens and focus is 40 cm. They are positive when the object or image is real. We carefully analyzes every step to ensure that our customers always to receive the best quality products. It can be of two types, i. Then altering the object distance to values less than one focal length produces images that are upright, virtual and located on the opposite side of the mirror. Plane mirrors and convex mirrors only produce virtual images. Be specific about the light bulb location.

Ray Diagram for the Formation of a Virtual Image A ray diagram for the case in which the object is located in front of the focal point is shown in the diagram at the right. Question 11: If we cover one half of the convex lens while focusing a distant object, in what way will it affect the image formed? Which of the following is correct? In fact, one generalization that can be made about all virtual images produced by mirrors both plane and curved is that they are always upright and always located on the other side of the mirror. Question 33: For finding the focal length of a convex lens by obtaining the image of a distant object, one should use as the object a a well lit distant tree b window grill in the class room c any distant tree d a lighted candle kept at the other end of the table Answer: a Explanation: The light and distance of the object is important consideration for correct focal length. A concave mirror can form both real, inverted images of various sizes and virtual, erect and enlarged images depending on the position of the object whereas a concave lens forms only virtual, diminished and erect images for all positions of the object. Virtual, erect and diminished images are always formed with convex mirrors, irrespective of the distance between the object and the mirror. But if we increase the distance between the object and the mirror then the size of the image reduces and a real image is formed.

## Convex Mirror vs. Concave Mirror

Question 7: How will you distinguish between a convex and concave lens? Question 3: What will be the nature of image formed by a concave mirror for a distant object? You can recognize these mirrors easily as the outward bulge is quite evident most of the time. Question 48: A student has obtained an image of a well-illuminated distant object on a screen to determine the focal length, f 1 of the given spherical mirror. The former brings together the parallel beam of light, while the latter disperses it. But plane mirror is not a diverging mirror, why does it not form a real focus. The derivations of the ray matrices of a convex spherical mirror and a are very similar.

We wish to describe the characteristics of the image for any given object location. The dentists use concave mirror to observe large images of the teeth of the patient. The main difference between a convex and concave mirror lies in the image formed by the two mirrors, i. If the distance of the screen from the device is 40 cm, select the correct statement about the device. The size of the image is larger as compared to that of the object. Light rays actually converge at the image location.

In which case will the student get more accurate value of focal length? Used as Rear view mirrors in cars and bikes. Question 40: Two plane mirrors are placed opposite to each other and a candle is placed in between, the image formed will be: a real and infinite b virtual and infinite c real and magnified d virtual and diminished. Regardless of exactly where in front of F the object is located, the image will always be located behind the mirror. Answer: c Explanation: The image formed is real and inverted. W hen the object is between the focus and the pole at a distance less than the focal length , The image is behind the mirror , The image is virtual , upright erect and magnified.

Shape Center of curvature Lies behind the mirror Lies in front of the mirror Type Diverging mirror Converging mirror Image Virtual image is formed. In this case, the image will be an upright image. W hen the object is at the focus , No image is formed , The image is at infinity where the rays penetrate as parallel. Reflections in a spherical convex mirror. A mirror is a surface which reflects a clear image. Step-by-Step Method for Drawing Ray Diagrams The method for drawing ray diagrams for concave mirror is described below.
