What happens to light rays when they enter a concave lens?
When light rays enter a concave lens, they diverge or spread out due to the shape of the lens. The lens causes the light rays to refract, so they do not come together at a single point like with a convex lens. This spreading out of light rays is what makes concave lenses useful for correcting myopia or nearsightedness.
A convex mirror will make light rays more what?
"A convex mirror is sometimes referred to as a divergingmirror due to the fact that incident light originating from the same point and will reflect off the mirror surface and diverge."So, a convex mirror will reflect and diverge (scatter) the incident light rays (it produces a virtual image), while a convex lens will do the opposite. It will converge light rays passing through it.
Why does an image disappear when it passes the focal point?
When an image passes the focal point of a converging lens, the light rays converge and then diverge. This causes the image to appear virtual and to shift position so that it is no longer formed on the other side of the lens. The change in direction of the light rays results in the image disappearing because the rays do not intersect to form a real image.
Does a diverging lens create a virtual image or a real image?
it will always create a virtual image because when you extend its light rays, they diverge and never end up intersecting. But if you extend these light ray backwards, they intersect to create a upright image which will always be virtual
When light strikes some objects the light bounces off of it these light rays are?
I believe you want to ask: what are the so-called "bounced-off" rays of light called? If so, the simplest answer would be: "reflections".
What part of your eye refracts light?
The retina which is where the image from the eye lens is focused. The retina is the reflective part of the eye. That's why cat's eye reflect so well, their retina are more exposed in the night because their pupils (or whatever they are in a cat) open wider than ours exposing more of that mirror at the back, the retina. Meeow!

Why does there look like there is water on the road when its hot out?
Because its probably a mirage. A mirage is an image of a distant object caused by refraction of light. The puddles on the road are light rays from the sky that are refracted to your eyes.Lets say there is a white car behind you and you notice shiny white areas behind the car. The air just above the road is hotter than the air higher up. Light travels faster in hot air. So light rays from the white car that travel toward the road are bent upward by the hot air. Your brain assumes that the rays travel in a straight line. So the rays look as if they have reflected of a smooth surface.

How a hand lens works?
a lens works when light goes through it and refracts (bends) inside the lens. so the light
How are light rays coming from a point source of light different then larger source?
From a point source, the light spreads out in all directions and adjacent light waves diverge from one another. From a larger source, it appears more like the light waves are moving parallel to each other, with little divergence. It's a relative thing. From the perspective of Earth, the Sun's rays are all parallel to each other because the Sun is huge and also because we are so far away from it. So the key differences are: 1. Small, point like source. 2. Being close to the source. Combinations of 1 and 2 above produce more divergent rays. Either of 1 and 2 below (or a combination of the two) will produce more parallel rays that don't diverge much. 1. Large light source 2. You're far away from the source.

What is the difference between real and virtual image?
Real image can be caught on a screen. But virtual cannot be caugtht so Real image is formed due to convergence of rays but in case of virtual there are only diverging rays and so they appear to diverge from one point where virtual image is located But both real and virtual could be seen by human eyes. Same way real object would definitely give out diverging rays But virtual object is considered as converging rays are assumed to come from such virtual object
Does concave lens produce a real image?
Because when you extend the light rays, they diverge and never meet. so you must always extend the light rays back behind the object, this will always result in the image being upright and erect. Meaning it will always be virtual, never real.
What are light rays used for?
so you can see .
