Which type of lens shrinks the image in front of it rather than magnifies it?

A diverging lens, also known as a concave lens, shrinks the image in front of it. This type of lens causes light rays to diverge, which results in the image being smaller than the object.


Why do goggle lens does not have any power even when they are curved?

Goggle lenses don't have magnifying power because the front and back of the lens is curved the same. Lenses only have refracting (magnifying or size-reducing) power if the front of the lens is curved differently than the back of the lens. If the curvatures produce a lens that is thicker at the center than at the edges, then it will magnify. A lens that is thinner at the center than at the edges will be size-reducing.


What is the behavior of light that causes msgnifying glasses and contact lenses to bend light rays?

The bending of light rays is called diffraction. It happens because light actually moves at different speeds in different substances. When light strikes a border between two substances (such as air and the glass of a contact lens) at angle, the edges of the wave-front reach the new substance at different times. Thus the different sides of the light ray change speeds at different times and the light ray bends.


Why are magnifying mirrors concave?

Magnifying mirrors are concave to focus light towards a specific point, creating a magnified image of an object held at a certain distance in front of the mirror. This curvature allows the mirror to form a virtual and upright image that appears larger than the actual object.


If images of distant objects are typically focused at a point in front of the retina?

The condition you are describing is called myopia, or nearsightedness. It occurs when the eyeball is too long or the cornea is too curved, causing light to focus in front of the retina rather than directly on it. This can be corrected with glasses, contact lenses, or refractive surgery to properly focus incoming light onto the retina.

Nearsightedness is caused by what?

Essentially it is because the lenses of the eye are too short, which focuses the light in front of rather than on the retina.


Describe the behavior of light that enables magnifying lenses and contact lenses?

The behavior of light that enables optical lenses to magnify images is called refraction. refraction is the bending of light. This happens when light enters a medium with a different "index of refraction." Index of refraction is a property of a material that measures how much the material's electric and magnetic fields interfere with light (which is an electromagnetic wave). This interference slows light down. The way I understand it, the front of the way slows down before the back of the wave, causing it to change trajectory like a bullet in water. The change in trajectory is a property of the geometry of the system of lenses which include the magnifying lens, lenses in your eye, and the object being magnified. You can find diagrams online of how this works.

Are most glasses lenses biconcave or biconvex and which corrects short sighted vision?

Most lenses are actually a meniscus design. the front curve is the base curve and the back side is either more or less curved than the base curve. Since most people are myopic (near-sighted) their lenses are usually a simple concave design rather than biconcave. Biconcave lenses are generally reserved for extremely high myopic prescriptions.

Contact lenses are placed on what surface of the eye?

Contact lenses are placed on the cornea of the eye, which is the transparent front surface covering the pupil and iris.


What causes short sight and how it can be fixed?

Myopia, or near-sightedness, is caused because the eyeball is too long in relation to the focusing power of the lens onto the retina. This causes the image to be focused at a point in front of the retina rather than on top of it. There are two ways to correct this: corrective lenses (eyeglasses or contact lenses) or surgery.


Bad oil leak on the front of your 5.7 Chevy engine you were told the front seal shrinks if left for ages help?

If the oil is leaking from the front seal you will need to remove the oil pan and replace both the front and rear seals and the rail gaskets.


Why is there no spark to front cylinder?

That rather depends on where the front cylinders are, and what they are on.
