Why can the image formed by a convex mirror not be projected on a screen?
The image formed by a convex mirror is virtual, meaning it appears to be located behind the mirror. Since the rays of light do not actually converge at a real point, they cannot be projected onto a screen. The image in a convex mirror is always smaller than the actual object and can never be brought to a focus.
How do you focuse the transverse section in order to get fine image?
How to focus the transverse section in order to get fine image
What do you call an object that produces a blurry image?
An object that produces a blurry image is called out of focus. This can happen when the camera or eye fails to properly focus on the subject, leading to a lack of clarity and sharpness in the resulting image.
What parts of the microscope is used to bring the image of the object on the slide into focus?
The fine adjustment knob is used to bring the image of the object on the slide into focus. It allows for small, precise movements of the lens to sharpen the image.
Difference between real and virtual focus?
A real image can be captured on a screen (eg white paper) whereas a virtual image cannot.To see an image on a screen light rays must come to a focus on the screen, but with a virtual image no actual light rays come together at the location of the image .. hence a virtual image cannot be seen on a screen.A real image is a source of light energy .. rays of light radiate from it.A virtual image is not a source of light energy.. rays of light do not radiate from it ( although it's where the brain 'thinks' the light originated.)
When the image of an object is brought into focus in front of a person's retina the defect is called?
Lens
When the image of a distant object is brought into focus in front of a person's retina. what is the defect?
nearsightedness.
When the image of a distant object is brought into focus in front a a persons retina the defect is called?
The image of a distant object is brought into focus in front of a person's retina, the defect is called nearsightedness. A virtual image produced by a lens is always located in front of the lens.

What is back focus and how does it affect the quality of an image?
Back focus refers to the distance between the back of a camera lens and the image sensor when the subject is in focus. If the back focus is not properly adjusted, it can result in blurry or out-of-focus images. This can impact the overall quality of the image by reducing sharpness and clarity.
What is the function of the coarse focus knob of the microscope?
To focus the image of the specimen
What are the steps to correct image that is not focus?
None. An image with wrong focus points can't be corrected, so you'll just have to take it again.
How does a magnifing glass work?
The image on a maginfying glass is that of the image on which the focus of the glass lies.
What are the properties of an image focus on the film in a camera?
The image is inverted and smaller than the object.
How do you focuse the transverse section in order to get fine image?
How to focus the transverse section in order to get fine image
Is a a convex lens focus light to form an image at the focal point?
Yes, it does focus light to form an image at the focal point and hence it is used in spectacles.
What do you call an object that produces a blurry image?
An object that produces a blurry image is called out of focus. This can happen when the camera or eye fails to properly focus on the subject, leading to a lack of clarity and sharpness in the resulting image.
