What does a negative 5 mean in eyesight?
The person is moderately myopic (short sighted or near sighted). The person can see things that are closer clearly but things that are far will be out of focus. The eye is bulged and the image forms in front of the retina and a concave lens with -5 power will help in forming a clearer image on the retina.
Why does a lens with with 2 cm diameter have 4 times the light gathering power of a 1 cm lens?
Because the 2cm lens has 4 times the area of a 1cm lens. (area = Pi*r2)
Which lens is greater than 50 mm?
a greater 1
Is convex lens have a positive or negative magnification?
Positive.Positive.Positive.Positive.
What is the volume of a lens?
V=1/3pi X^2(3r-X)
Lens that gives an enlarged image?
A magnifying lens is designed to give an enlarged image of an object when viewed through it. This lens works by bending light rays to converge on the eye, creating a larger image on the retina. Magnifying lenses are commonly used for tasks such as reading small print or examining details in objects.
Which type of image does a concave lens form?
A concave lens forms a virtual and diminished image. The image is produced on the same side as the object and is smaller in size.
Which parts of a microscope forms an enlarged image of a specimens?
The objective lens forms an enlarged real image of the specimen, which is further magnified by the eyepiece to produce a final enlarged image for observation.
If an object is closer to a convex lens than one focal length the image is .?
If an object lies within the focal length of a convex lens, its image will be erect, bigger in size and virtual. It will be on the same side of the object.
What has a objective lens that creates an image of the object that is enlarged by the eyepeice?
A microscope has an objective lens that magnifies the image of an object, which is then further enlarged by the eyepiece for viewing. This combination of lenses allows for detailed examination of small specimens.
What can form an enlarged image?
Well, if you say sausage king and bow three times, that's usually how I make the watermelon seeds disappear.
What kind of image is formed by a concave image?
image formed by the concave lens will be erect , virtual and smaller than the size of object.
Why is convex lens also called magnifying glass?
as they shows the image in enlarged size
Convex lensWhat type of image is seen from the lens?
A convex lens can produce both real and virtual images. Real images are formed when light rays converge at a point in front of the lens, while virtual images are formed when the diverging rays appear to originate from a point behind the lens. The type of image produced depends on the object's position relative to the focal point of the lens.
Where will place an object to see an erect magnified image?
You should place the object closer to the converging lens at a distance less than the focal length to see an erect magnified image.
What image does a concave lens produce?
A concave lens produces a virtual, upright, and diminished image for an object placed beyond its focal point. The image will appear on the same side of the lens as the object.
What type of image is produced by a converging lens on the screen?
A converging lens produces a real image on a screen when the object is placed beyond the lens's focal point. The image is inverted and can be larger or smaller, depending on the distance between the object and the lens.
