# What is the size of the image if the object is located between F and 2F in a convex lens?

## What is the size of the image if the object is located between F and 2F in a convex lens?

Complete answer: From the above ray diagram we can observe that If we place the object between F(focus)and 2F the image formed is always beyond 2F. The images are real and always inverted.

## What is the size of the image if the object is located at the focus?

Reflection from a Concave Mirror The image is real light rays actually focus at the image location). As the object moves towards the mirror the image location moves further away from the mirror and the image size grows (but the image is still inverted). When the object is that the focal point, the image is at infinity.

What will be the size of an image if the object is located at the curvature?

At the center of curvature, the object distance equals the image distance and the object height equals the image height. As the object distance approaches one focal length, the image distance and image height approaches infinity. Finally, when the object distance is equal to exactly one focal length, there is no image.

At what object distance the image is of same size as the object?

Explanation: Same size of image is formed by a convex lens only when the object is placed at a distance u=2f from the optical center and image is also formed at distance 2f on other side of lens.

### What is the location of convex between 2F and F?

Image Characteristics for a Convex Lens

Object Position Image Position
At 2F At 2F
Moving from 2F toward F Moving from 2F toward infinity
At F At infinity
Moving from F toward lens Moving from -infinity toward lens

### Is 2F C in lens?

Answer: Yes the centre of curvature C and 2F are same. The centre of the curvature of the spherical lens is at the double of the focal length from the pole of the mirror located on the principal axis.

What is image distance?

Image Distance, s’, is the distance from a lens or mirror to an image. • Magnification, m, is the amount of size increase (or decrease) of the image as compared to the object. m = hi /ho • Images are formed by lenses and mirrors where light rays cross or focus.

What is the size of the image when an object is kept at infinity in front of the convex mirror?

2 Answers. When the object is placed between the infinity and the pole of a convex mirror, the ray diagram will be as follows : The image formed will be behind the mirror between P and F. So the image is virtual, erect and diminished.

## What is the size of the image?

Image size: This represents the physical size and resolution of an image measured in pixels. For example, A 10 megapixel (MP) camera may provide settings to take pictures in 10.2 MP (3872 x 2592), 5.6 MP (2896 x 1944), and 2.5 MP (1936 x 1296). A higher image size setting means a larger picture and bigger file size.

## What is R 2f in physics?

R is the radius of curvature and f is the focal length of a spherical mirror. For spherical mirrors of small apertures, the radius of curvature is found to be equal to twice the focal length, i.e., R = 2f. This implies that the principal focus of a spherical mirror lies between the pole and the centre of curvature.

In which case we will get same size image?

The correct answer is option 3, i.e. Object placed at Center.

When you will get same size image for a Convexlens?

Answer: Same size of image is formed by a convex lens only when the object is placed at a distance u=2f from the optical center and image is also formed at distance 2f on other side of lens.

### What is the difference between the size of image and object?

The size of the image is the same as compared to that of the object. When an object is placed in between the center of curvature and focus, the real image is formed behind the center of curvature. The size of the image is larger than compared to that of the object. When an object is placed at the focus, the real image is formed at infinity.

### Where is the real image formed on a mirror?

For a real object close to the mirror but outside of the center of curvature, the real image is formed between C and f. The image is inverted and smaller than the object. 3.) For a real object at C, the real image is formed at C. The image is inverted and the same size as the object.

What is the position of the image formed at F?

For a real object at f, no image is formed. The reflected rays are parallel and never converge. 6.) For a real object between f and the mirror, a virtual image is formed behind the mirror. The position of the image is found by tracing the reflected rays back behind the mirror to where they meet. The image is upright and larger than the object.

How many types of images are formed when the object is placed?

Different types of images are formed when the object is placed: 1 At the infinity 2 Beyond the center of curvature 3 At the center of curvature 4 Between the center of curvature and principal focus 5 At the principal focus 6 Between the principal focus and pole
