A magnifying glass is an optical instrument that uses two convex lenses to allow you to see very small objects. The first lens enlarges the image of the object, and the second lens further magnifies the image for observation.

What are the uses of convex lenses in optical instruments?

They're caved-outward shape allows the focused object to appear backward or upside down. They also magnify various objects, which is useful for magnifying glasses and telescopes.


What tool has a convex lens?

A magnifying glass is a tool that has a convex lens. The convex shape of the lens allows it to magnify objects when they are viewed through it.


What two optical devises use convex lenses to focus and enlarge images?

A magnifying glass uses a convex lens to focus and enlarge small objects, while a camera uses a convex lens to focus and enlarge images onto film or a digital sensor.


Does a thinner and less convex lens have a shorter focal length and low optical power?

It is not necessary that a thinner convex lens have less optical power or a thicker lens has more optical power


What two optical devices use convex lenses to focus and enlarge images?

An optical microscope or twlescope.


Do convex lens make them bigger?

A convex lens can magnify objects when they are placed closer to the lens than their focal length. However, the size of the object itself remains the same. The lens allows you to see the object as if it were larger by converging light rays to create a magnified image.


What optical components does a camera use?

Convex and concave lenses, and prisms.


What is a piece of curved glass that magnifies objects?

A piece of curved glass that magnifies objects is called a lens. Lenses can be convex or concave; convex lenses bulge outward and converge light rays, making objects appear larger, while concave lenses curve inward and diverge light rays. They are commonly used in optical devices like glasses, cameras, and microscopes to enhance visibility and detail.

What is the effect of the convex lens in experiment the liquid lens?

In an experiment using a liquid lens, the convex lens helps to focus the light passing through the liquid lens. This allows for the manipulation of the shape of the liquid lens which can change its focal length. By adjusting the curvature of the liquid lens and using the convex lens, the overall optical properties of the system can be controlled for various applications.
