Is magnification enlarged or diminished?
Magnification is the ratio of the size of the image and the size of the object. But this does not mean that the image is only enlarged.
How do you tell if an image is magnified or diminished Class 10?
Answer
- If magnification is <1.
- If magnification is >1.
- If magnification is equal to 1.
- If the value e get is negative this means that the image formed is real and inverted and if we r getting point values then the images will be of diminishd.
- If the value is positive it means that the image formed if virtual and erect.
How do you know if an image is enlarged or reduced?
so, if the height of the image so formed is less than that of the height of the object or value of m is less than 1, then the image is diminished and when the height of image is greater than height of the object or m>1 , then a magnified image is formed.
How do you know if an image is diminished?
If an image is smaller than the original object it is called diminished and if it is larger it is called magnified. Diminished Image: If the image produced is smaller than the original object, the image is called dimished. An example of this is an object placed far from a convex lens.
What does it mean when an image is diminished?
If the size of the image formed is smaller than the object, the image is said to be diminished. If an image is smaller than the original object it is called diminished and if it is larger it is called magnified. diminish. Diminish means to make smaller or lesser.
Can a real image be diminished?
The image formed by a concave lens is always virtual, erect and diminished. The image formed by a concave mirror can be real or virtual, enlarged or diminished, and erect or inverted, depending upon the distance of the object from the mirror. The image that can be obtained on a screen is called a real image.
What is the difference between magnified and diminished image?
Diminished image’s size is smaller than the size of the object, whereas the size of a magnified image is larger than the object. The diminished image is usually formed in front of the mirror and the magnified image is usually formed behind the mirror.
Are real images inverted or upright?
A real image occurs when light rays actually intersect at the image, and is inverted, or upside down. A virtual image occurs when light rays do not actually meet at the image. Instead, you “see” the image because your eye projects light rays backward. A virtual image is right side up (upright).
What can only form diminished image?
An image formed by a concave lens cannot be obtained on a screen. The image formed by a convex mirror is always diminished and erect. Convex mirrors form real images when the object is right on the mirror surface….Thank you.

How is a diminished image formed?
A real and diminished image of an object can be formed on a screen by the convergence of light rays coming from an object and is possible only with a convex lens or a concave mirror and placing the object at a distance beyond twice the focal length of the lens or mirror.
What can produce diminished virtual image of a real object?
A convex mirror always produces a diminished virtual and erect image for a real object.
Which Cannot produce virtual image?
Concave mirror converges the ray of light reflecting from it to form a real image. But if the object is placed between the Pole(P) and Focus(F) of the mirror, then virtual image is formed behind the mirror.
Why real images are always inverted?
Real image is found when the rays of light converge at a point after reflection on a mirror or after refraction through a lens. If we placed an object above the x-axis then by geometry the rays will converge below the axis. Therefore, the image formed will be an inverted image. Hence, a real image is always inverted.
Can we see virtual image?
Virtual images can be seen directly without using a screen for projection. The virtual image produced by a plane mirror. The virtual image produced by a convex lens when the source is closer to the lens than the focal length, f. Note that the virtual image is magnified and upright compared to the object.
Is the image formed by a plane mirror real or virtual?
Real Images. In the case of plane mirrors, the image is said to be a virtual image. Virtual images are images that are formed in locations where light does not actually reach.
What type of image is formed in a cinema screen?
Complete answer: When the light rays from a source of light strike the surface of a concave mirror then it converges the light rays to a single point. Since the image formed on the cinema screen is always formed due to the actual meeting of rays, so a concave mirror is used on a cinema screen.
How can you prove to someone that an image is a real image?
In a concave mirror, the image is real if the distance of the object from the mirror is greater than the focal length and virtual if it is less than the focal length. If the object is at the focus the image is formed at infinity. In a convex mirror, the image is always virtual.
