How does light travel through concave and convex lens?
In a concave lens, light rays diverge after passing through the lens, causing image formation behind the lens. In a convex lens, light rays converge after passing through the lens, resulting in image formation on the opposite side of the lens. The specific path of light through these lenses is determined by the refraction of light rays at the surfaces of the lens.
How does the object distance of a convex lens compared with the object distance of a concave lens?
The object distance of a convex lens is measured from the optical center to the object, while for a concave lens, it is measured from the optical center to the object along the path of light. In general, the object distance for a convex lens is positive, while for a concave lens, it is negative since the object distances are measured on the opposite sides of the lens.
What does an incident ray that passes through the vertex of a convex lens do?
An incident ray that passes through the vertex of a convex lens will continue in a straight line without being refracted. This is because the lens is thinnest at the vertex and has minimal effect on the path of light passing through this point.
What happen when put convex and concave With some?
When a convex lens and a concave lens are placed together, they can form a compound lens system known as a lens system. Depending on the relative orientations and distances between the two lenses, the resulting system can either magnify, diminish, or correct the incoming light rays. This configuration is commonly used in optical instruments such as microscopes and telescopes to manipulate the path of light rays.
What is the Nature of a convex lens immersed in a liquid with a refractive index same as of glass?
The "nature" of it is the same as if it weren't immersed. However, if it has the same refractive index as the material it's immersed in, it will no longer have any discernable effect on the refraction of light; from the outside it will appear to just be another part of the liquid (it may well disappear from sight, since it's no longer visually distinguishable from the liquid itself).

Which correctly describes the path of a light ray that passes through a convex lens parallel to the major axis?
The light ray will bend towards the major axis, aiming for the focal point.
What is the similarities between concave and convex lenses?
A lens and a mirror both serve to bend light in a particular way. A lens bends the angle at which the light goes, while a mirror reflects the light away.
Curved glass that bends light rays?
Curved glass bends light rays due to refraction, where the change in speed of light as it passes from air to the glass causes it to change direction. The curvature of the glass surface also plays a role in how the light is refracted, which can be used in technologies like lenses and curved displays to manipulate the path of light.

How light rays traveling parallel to the optical axis are bent after they pass through a convex lens?
When light rays travel parallel to the optical axis and pass through a convex lens, they converge at a focal point on the opposite side of the lens. This is due to the convex shape of the lens causing the light rays to refract towards the center of the lens. The point at which the light rays converge is known as the focal point, and the distance between the lens and the focal point is called the focal length. This phenomenon is governed by the lens equation, which relates the object distance, image distance, and focal length of the lens.
Can you change the path of light?
use a mirror to change the path of light.
Why does a convex lens converge the rays that fall on it and a concave lens diverge the rays that fall on it?
Better to understand how the shapes of the wavefronts of light change when they pass through the lens(concave or convex) in terms of Huygens Principle? The simple answer is that light travels in a straight line in any given medium. A medium could be anything light can pass through like air, vacuum, water, glass, plastic. Each medium has its own 'refractive index' which is a physical property of the material that varies the speed of light within a medium. Light travels slower in glass than it does in air for example. Light bending or refraction occurs as light passes the boundary of one medium into another. When viewing light from an object through a lens, that light passes from the object through air to the lens material and back into the air before reaching they observers eye.Light rays entering the front convex or concave surface of a lens are refracted (bent) by the refractive index of the lens to a new path through the lens material. As light leaves the lens material it is bent again as it reenters the air. The extent that light rays bend depends on the lens material and the curvature of the lens surfaces. Light entering a convex lens is refracted toward a focal point on the other side of the lens. Light at the edges bends more than light passing through the center of the lens, however all rays converge at the focal point. If an observer were to place their eye just in front of the focal point the image would appear larger and in the same orientation. If an observer places their eye beyond the focal point the image appears inverted.Light entering a concave lens is refracted away from a focal point making the image appear smaller.
Why does the shape of the eye lens change?
This adjustment is done by two sets of muscles in the iris: its circular muscles contract to close up the iris, making the pupil smaller - while its radial muscles contract to open up the iris, making the pupil larger.
