Anything which gives out light rays is called object . ( eg – bulb, candle and etc. ) Image : is an optical appearance produced when light rays coming from an object are reflected from a mirror ( or when two light rays meet )

What is an image in physics class 10?
Image : When light rays meet or appear to meet after reflection from a mirror,then it is called an image.
What is image in physics example?
When the light rays coming from an object appear to meet at a point after reflection or refraction, the point may be defined as an image. The word object in the definition can be anything that emits light rays. As light is emanating from an object in a variety of directions, an image is formed.
What is called image?
An image is a visual representation of something, while a digital image is a binary representation of visual data. These images can take the form of photographs, graphics and individual video frames. For this purpose, an image is a picture that was created or copied and stored in electronic form.
What is an image in physics class 12?
An actual image is the combination of focus points formed by converging rays, while a virtual image is the combination of focus points made by expansions of diverging rays.
What is real image class 9?
A real image is formed when the rays of light after reflection or refraction actually meet at some point whereas a virtual image is formed when the rays of light after reflection or refraction appear to meet at a point.
What is an image in physics class 6?
Image is formed by the reflection of light rays by an object. Image has the colour of the object. An image gives the details as well as the outline of the object.
What are the types of image in physics?
There are two forms of image real image and a virtual image. The difference between the real image and a virtual image is the way they are produced. To obtain a real image, the light rays converge while to obtain a virtual image, the light rays diverge.
How is image formed?
An image is formed by reflection when two or more reflected rays of a point meet at a single point. The image is formed at the point of intersection of the reflected rays.
What is an image class 7?
An image is an optical representation of an object. An image can be either real or virtual. The images that can be formed on a screen or called real images. The images that cannot be formed on the screen are called virtual images.
What is an example of image?
The definition of an image is a representation of something or someone or a photograph or an idea you’re picturing in your head or the way you or others think of you. An example of an image is a painting of your father. An example of image is a picture taken with a camera and developed.
What is image type?

- TIFF – Tagged Image File.
- PSD – Photoshop Document.

What is real image class 10th?
A real image is defined as one that is formed when rays of light are directed in a fixed point. A real image can be projected or seen on a screen. The best example of a real image is the one formed on a cinema screen.
What is an image Question Answer?
Image questions allow you to show a visualization of the answer options for respondents to review and select. Instead of selecting a radio button, respondents can scroll over the image and pick the one that best suits their answer.
Is image an object?
difference between object and image. is that object is a thing that has physical existence while image is an optical or other representation of a real object; a graphic; a picture.
What is the difference between image and object in physics?
The difference between object and image is that the object is a thing that has physical existence while an image is an optical or other representation of a real object, a graphic; a picture.
What is difference between image and shadow?
Hint: We know that an image is a picture of an object while shadow is formed an object comes in between the surface and light.
What is called real image?
A real image occurs where rays converge, whereas a virtual image occurs where rays only appear to diverge. Real images can be produced by concave mirrors and converging lenses, only if the object is placed further away from the mirror/lens than the focal point, and this real image is inverted.
What is real image with example?
In a real image the light rays actually are brought to a focus at the image position, and the real image may be made visible on a screen—e.g., a sheet of paper—whereas a virtual image cannot. Examples of real images are those made by a camera lens…
What is a mirror in physics?
A mirror is defined as a reflecting surface and can be explained by the law of reflection, which states that when a ray of light is made to fall on the reflecting surface, the incident ray, the reflected ray and the normal to the surface of the mirror all lie in the same plane and the angle of incidence is equal to the …
How is an image formed Class 6?
Image formation by a plane mirror: We are able to see images through a mirror. Image formed by a mirror (flat) has following features: Reflected image retains the colour of the object. Image is erect but laterally inverted.
What is image in mirror?
A mirror image (in a plane mirror) is a reflected duplication of an object that appears almost identical, but is reversed in the direction perpendicular to the mirror surface. As an optical effect it results from reflection off from substances such as a mirror or water.
What is the difference between image and shadow 2?
Images have colour, unlike shadows. They are formed due to the converging rays of light that comes after reflecting from objects. A shadow is formed when an opaque object comes in the path of light. Shadows give us an idea about the shapes of different objects.
How many types of image are there?
The five types of images are jpg/jpeg, tiff, png, gif and raw image files. Each of them has its own unique features. While tiff and png images have large sizes, jpeg and gif images are relatively small in size.
What is virtual image in physics?
Virtual image refers to the image which forms when the light rays appear to meet at definite point, after reflection from the mirror. An erect image is one that appears right-side up. An erect image is formed by the actual intersection of rays.
