Which mirror is used in solar cooker Concave or convex mirror or concave lens or convex lens?
convex mirror is not used in solar cooker since it form image inside the polished surface
What is a concave lens?
A lens that is thinner in the middle and thicker at the edges is called a concave lens.
What is a sentence for concave lens?
A Concave lens is used to correct short- sightedness.
How do you use concave lens in a sentence?
A concave lens is thinner at the centre. People who are short sighted often use a concave lens to help them see better.
What type of lens is used to correct nearsighted vision?
Using concave lens the short sight problem could be rectified. Near sighted person cannot see the things far away. He can see things only so near to his eyes. The ray coming from the far object would form an image just before retina since the eye ball is elongated horizontally. So to make the image to move backward and fall on the retina, a concave lens is used to diverge the ray and finally the image would fall on the retina. Thus the remedy is possible with concave lens.
What is an optical device that uses a lens to produce a larger and virtual image?
A camera, television, lap top, glasses, psp, claw machine.
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.
Because the light rays never meet a concave lens can produce?
Because the light rays never meet, a concave lens can produce only a virtual image.
What kind of lens can be used to produce a virtual image?
Convex lens produces both real and virtual images. But concave lens produces only virtual images for real objects. If object is virtual then real image could be produced by a concave lens.
What are the Lens that can create a real or virtual image?
Convex lens. Concave lens would give only virtual image for real objects.
What image does a concave lens produce?
real or virtual imagevirtual,erect anddiminished
How concave lens produce real image for virtual object?
As it produces images which are reflected in a surface.
Why can a concave lens produce only virtual image?
it can only produce virtual images because whenever an object is placed, a virtual image forms
How is the image formed by a concave lens similar to the image formed by a convex mirror?
In a concave lens the object always forms a virtual image. The convex lens also forms a virtual image.
How does light refracts as it travels through a concave lens?
What type of image can a concave lens form
How do convex and concave lenses affect the attitude and appearance of an image?
Convex lens is a converging lens It makes the image real and inverted whereas concave lens is a diverging lens it makes the image virtual and erect.
What kind of image does a converging lens produce?
A real image as well as a virtual image.
