What makes an object appear larger through a magnifying lens?
Because of the phenomenon of refraction. Light as it travels in a medium would travel at a constant speed. But as it changes from one medium to another due to the change in its speed it gets refracted from its original path. This makes the object to look enlarged as it is placed in between the principal focus and the optic centre of a convex lens.
What happens to the path of light as it strikes a mirror and then a hand lens?
It is reflected at an opposite angle, and focused by the lens.
What does concave lenses do to light rays?
a concave lens diverges the light ray travelling in a straight parallel path.
How does a lens form image?
It changes the path of the light rays (or rather the photons) radiating from the object in question.
Discuss how incident rays are refracted by a concave lens?
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.
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.
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.
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.

Can you change the path of light?
use a mirror to change the path of light.

Is the inverted image created by a lens also inverted horizontally?
For a convex lens, if you trace out the path of the rays as they are refracted through the lens, you'll see that the inverted image gets reversed horizontally as well as vertically (in other words, the "inverted" image is really a 180 degree rotation about the axis through the center of the lens).
