What lens used to correct nearsightedness?
Convex lenses are thicker in the middle then the edges and concave are thicker at the edges then the middle. When light travels through lenses, refraction occurs. The light bends either outward or inward, it depends on the lens.The lens of your eye is a double convex lens. Its job is to focus the image on the retina of the eye. If one is farsighted, the lens in the eye causes the focus to be behind the retina. These people see far but have some difficultly seeing close-up.To correct this farsightedness, the person would wear glasses or contacts with convex lenses, for It is often used for close examination of small objects.
What is an intense focused light of similar wavelengths?
A LASER is very intense. It only has one frequency of light. It can be spread out and focused using lenses.
Why convex lens are used in huge shopping center?
Conver lenses curve to capture more light. Putting a relective surface on such a lensr allows for more images to be captured without using large mirrors. Essenially these mirors allow for security or personel to view a large portion of a store with less reflective surface.
How are magnifying lenses constructed?
Have you ever wondered how a magnifying glass is constructed? A magnifying glass is constructed by using a convex lens to curve and magnify objects. A magnifying glass is also constructed out of glass.
How will you distinguish between a convex and concave lens using a printed piece of paper?
the image formed by convex lens will converge at a point, while with a concave lens it will appear to diverge from a point.
What would an image look like using two convex lenses?
Blurry depending on who is looking through the lenses.
What are some ways using convex and concave lenses to form an image that is smaller than the object?
For forming a smaller image than the object using convex and concave lenses, you can place the object closer to the convex lens than its focal length, then position a concave lens closer to the convex lens than the sum of their focal lengths. This arrangement will produce a smaller inverted image. Adjustments can be made by changing the distances between the lenses to fine-tune the size and position of the image.
Why are the images under the light microscope are reversed and inverted?
The microscope you are using is probably old, and it has an odd number of convex lenses between the object and your eye. in addition to enlarging (or reducing) an image, an optical convex lense also inverts the image. If you were to invert the inverted image again, using another lense, then the resulting image will appear upright. So a microscpope with three lenses (most likely the number of lenses in the microscope you are using) inverts the image three times, resulting in an upside-down image. A microscope with four lenses shows an upgright image. That is why modern microscope manufacturers use an even number of lenses in a microscope (and in binoculars).

What is a tool that gathers light with mirrors and lenses called?
Cameras and reflecting telescopes gather light using mirrors and lenses.

Is it possible to make a gun using concave and convex lens?
Yeah ,for aiming purpose that is for taking target ,but to make gun out of lenses ,it is impossible.
Why was JKepler famous?
Johannes Kepler(1571-1630), suggested in 1611 that using convex lenses within the eye piece and a convex lens in the objective would help improve the image. However, he never attempted to make this microscope.
How do you find the power of lenses using focal lengths?
Power (F)= 1/focal length (f) focal length f, is measured in meters the power, F, is in dioptres (D) In converging or convex lenses the power is positive In diverging or concave lenses, the power is negative :)
What has the author Wilfrid Llowarch written?
Wilfrid Llowarch has written: 'Using light' -- subject(s): Lenses
Telescope collects and focuses light using a mirror?
Yes, or lenses. Called reflector and refractors respectfully.

A LASER is very intense. It only has one frequency of light. It can be spread out and focused using lenses.
