Raster images lose quality when enlarged because they are made up of a fixed grid of pixels. When enlarged, the individual pixels become more visible, resulting in a blurry or pixelated image.

What type of image is formed by a refracting telescope -?

an enlarged, upside-down virual image.


Which mirror shows enlarged image?

A concave mirror shows an enlarged image. This type of mirror curves inward and causes light rays to converge, resulting in an image that appears larger than the actual object.


Which type of image can be enlarged without becoming blurred?

Vector images can be enlarged without becoming blurred because they are based on mathematical equations that allow them to be resized without losing quality. This is in contrast to raster images, such as JPEG or PNG files, which become blurry when enlarged because they are made up of a fixed grid of pixels.


Which type of mirrors are used to give an erect enlarged image of an object?

Concave mirrors are used to give an erect and enlarged image of an object. The image formed is virtual, upright, and magnified when the object is placed between the focal point and the mirror's surface.


What type of mirror would you use to view an enlarged image of an object?

You would use a concave mirror to view an enlarged image of an object. Concave mirrors can focus light rays to create a magnified image that appears larger than the actual object.


What type of image retains its quality after resizing?

You can retain 100% quality only with vector graphic. When resizing pixels you can never retain 100% quality, some pixels will be added or deleted depend on type of resizing: downsampling (make image smaller) or upsampling (make image larger).


What type of zoom results in increased magnification without a change in image quality?

Optical zoom results in increased magnification without a change in image quality because it physically adjusts the lens to zoom in on an image. This is different from digital zoom which enlarges the pixels of an image resulting in reduced image quality.


What type of mirror is used whenever a magnified image of an object is used?

A concave mirror is typically used to create a magnified image of an object. The mirror curves inward and can produce an enlarged virtual image when the object is placed within the focal length of the mirror.


What type of image is formed by a mirror if m 5.2?

If the magnification factor (m) is positive (greater than 1), then the image is upright and enlarged. If the magnification factor is negative (less than -1), then the image is upright and reduced. If the magnification factor is between -1 and 1 (excluding 0), then the image is smaller and inverted.


What type of image is formed in a cinema screen?

An enlarged virtual image is formed on the cinema screen through the projection of light from the film or digital source. This image is created by focusing light rays onto the screen, allowing viewers to see a larger and clearer representation of the content being displayed.


Which kind of microscope magnifies specimen to produce the virtual image of the specimen?

A virtual image of a specimen is produced by an optical microscope, which magnifies the specimen using lenses to create an enlarged view that is visible to the human eye. This type of microscope does not require direct contact between the specimen and the lens, hence producing a virtual image.


How does compression effect images?

Any type of compression will ideally reduce the size of an image. There are two types of compression which describe how they affect images:"Lossy" compressionThis type of compression reduces the size of the image by removing some data from it. This generally cause, effect the quality of the image, which mean it will reduce your image quality."Lossless" compressionThis type of compression reduces the size of the image by changing the way in which the data is stored. Therefore this type of compression will make no changes in your image.
