What is the difference between an object and an image?
An image is an optical representation of an object.... Object is real... while image is not... i thnk the word imaginary fits for image.... we can take example of our shadow... when light falls on us ( object ) it creates an image (shadow ) in the ground....
What is the difference between Shadow and image?
A shadow does not show the details of the object whereas an image shows the exact details of the object.A shadow is formed due to blocking of light by an opaque object, while the image is formed due to reflection from an opaque, smooth and shiny surface.A shadow is always dark while the image shows true colors of the object.
What is image space and feature space in remote sensing?
The image space is the 2D plane of the image where pixels are located. It represents the spatial space of the image. In other words, when we talk about the location of each pixel in an image, we are talking about image space. On the other hand, feature space is about the radiometric values assigned to each pixel. In case of a grey-scale imagery, only one radiometric value is assigned to each pixel. When we say an image is RGB or multispectral, then each pixel has several radiometric values that are stored in different channels (for instance there are 3 channels of Red, Green and Blue in an RGB image, so for a pixel we have 3 radiometric values). Feature Space is the space of these radiometric values; the radiometric values of each pixel can be plotted in that space and you can create a feature space image. Last example, an RGB image has a 3 dimensional feature space while it still has a 2D image space.
How does light become an image?
In the eye, light becomes a visible image due to the organs in the back of your eye called 'cones and rods'. These are situated along the retina, inside the eyeball. Cones pick up colour, while rods pick up shades of black and white, and how light or dark a certain image will appear. The light image that is made in the eyeball is actually upside down when it is sent along the optic nerve to the brain (as electric pulses) because the lens in your eye is convex which, when light passes through it, refracts light so the end image is an upside down replica. The brain then flips the image upside down, which becomes the image you see. People become colour blind when they are missing certain colour receptors, which register the 3 primary colours red, blue and green. **Side note: 1 in every 15 men are colour blind, while only 1 in 1000 women are.**
What is the reason you see a red white and blue flag after staring at a yellow green and black flag is called?
It's a 'complimentary image'. You're seeing the 'opposite' colours for a short while.
example of grammatical accuracy while speaking?
Speaking with correct subject-verb agreement, using proper tense and word order, and avoiding run-on sentences are examples of maintaining grammatical accuracy while speaking. Maintaining clarity and coherence in speech also contributes to grammatical accuracy.
How much can a microscope magnify?
it depends on wat microscope you have. some can magnify up to 2 billion times while others can only magnify up to 2000.
What are the differences with a telescope and a microscope?
the microscope can magnify even the smallest organism while the telescope magnify only in a little distance
Is there a difference between an image scanner and a document scanner?
The difference is mainly in the software. Document scanners use OCR technology focused on recognizing and converting text, while image scanners' software is geared towards maintaining image fidelity from photos, etc. Yes there is. A document scanner uses OCR to recognize characters in paper documents and convert them to digital form, while an image scanner is focused on maintaining the quality of images scanned in with less thought to text recognition.
What the difference between amplification and magnification?
Amplification is often associated with sound, electricity and other wave phenomena.Magnification is often associated with size and dimensions.Examples:If you amplify the light it will get brighter; while if you magnify an image it will get larger.
What are some solutions to maximize the clarity for an acoustic concert?
To maximize the clarity and overall sound quality of an acoustic concert there is a strong need for refractive barriers for the sound to hit. Without an enclosure a majority of the sound is going to be lost. Speakers can be used for larger venues while maintaining the intimacy of an acoustic set.
How are a microscope and a telescope different?
Both microscopes and telescopes use lenses to magnify objects. But, telescopes are large and collect light from stars and planets to magnify them, while microscopes are small, can sit on a desktop, get light from the room or a small builtin light and are used to magnify tiny objects.
How are a microscope and a telescope alike?
Both microscopes and telescopes use lenses to magnify objects. But, telescopes are large and collect light from stars and planets to magnify them, while microscopes are small, can sit on a desktop, get light from the room or a small builtin light and are used to magnify tiny objects.

How long is a 2 page summary?
A 2-page summary typically consists of 500-800 words, depending on formatting and font size. It should succinctly capture the main points and key ideas of a longer text while maintaining clarity and coherence.
How did the compound microscope help the scientists in discovering the cell?
It allowed them to observe the cell via direct magnification. Single lenses powerful enough to reach this level of magnification would be impractically large, while small compound lenses can magnify the image using progressive refraction.
How do you restate a sentence?
Restating a sentence involves expressing the same idea using different words or phrasing. This can be done by changing the sentence structure, synonyms, or word order while maintaining the original meaning. It helps to ensure clarity and variety in writing.
