No because the waves don't cross
Yes it does. It's called a negative focal length, because parallel light rays viewed after passing through the lens appear to come from a point on the incident side. If you go to buy a concave lens, the first question you will be asked is "what focal length?"

No it don't. Concave lens make words appear smaller. I tested it out in science class. We are working with lens so trust me.

Difference between focal point and focal length?
The focal point is the point where light converges after it passes through a concave lens. The focal length is the distance of the focal point to the lens. Same for a convex lens, except that the focal point is the imaginary point from where light deflected from lens seems to have emerged.
A concave lens bends light towards its what?
Focal point.
Why is the focal point of a convex lens real and that of a concave lens virtual?
because in a convex lens rays join at a common point after refrection but in case of a concave lens they appears to come from a common point.
What creates an image that is reflected through a focal point?
a convex lens
Why is concave lens called a negative lens?
Concave lens is called a negative lens because it has a negative focal length.

Which lens and which mirror forms a visible focal point?
A concave lens and a convex lens are what you're looking for. / | ∙ \
Why doesn't a concave lens have a focal point?
because it is not refracted or reflected

What is the positive lens is the same as?
The focal point F and focal length f of a positive (convex) lens, a negative (concave) lens, a concave mirror, and a convex mirror. The focal length of an optical system is a measure of how strongly the system converges or diverges light.
What creates an image that is reflected through a focal point?
a convex lens
Why is concave lens called a negative lens?
Concave lens is called a negative lens because it has a negative focal length.
What is the difference between the way parallel light rays are affected by a concave mirror and a concave lens?
The difference between the two is that once the light passes through the concave lens it diverges, and the rays are refracted outward, and never meet a focal point. Then there is the parallel light rays that bounce off the curved surface of a concave mirror and then meet a single point ( focal point).
A concave lens is kept in contact with convex lens of focal length 20cm the combination works as a converging lens of focal length 100cmcalculate the power of concave lens?
i think it is -0.06m i.e. 6cm
Why is convex lens used for myopia?
Convex lenses cause the focal point to appear behind the lens (positive convergence). In myopia, the focal point lies somewhere between the lens and the retina, it needs to converge at a point farther than it is converging, this is why a convex lens is used, to push the focal point back so it will hit the retina. A concave lens would do the opposite for hyperopia (the focal point appears behind the retina), it will adjust the focal point to lie more anteriorly and land on the retina.
