IF you meant a convex lens - light entering the lens is bent because it's passing from one medium to another - to converge at the focal point.
F22 - All the lenses I have for my 35mm camera have an F22 setting, this lets the least amount of light through the lens.

Reflecting TelescopeA reflecting telescope uses a lens and two mirrors. The lens is positioned at the eyepiece, and thus the focus, which the two mirrors generated by specifically redirected light. There are two types of reflecting telescopes with one lens and two mirrors, the Newtonian Focus and the Cassegrain Focus.
Eyepiece lens.
simple microscope only have 1 lens and compound microscope uses 2 lens \
Air.
In a concave lens, light rays diverge after passing through the lens, spreading out away from each other. In a convex lens, light rays converge after passing through the lens, coming together at a focal point.
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.
All colors of light travel at the same speed in a vacuum, including through a telescope lens. The speed of light is determined by the medium it travels through; in air or a lens, all colors of light travel at the same speed.
When they are entering a concave lens they are refracted and bend away from each other.
No, not all light waves that travel through a convex lens pass through the focal point. It depends on the wavelength of the light, since light of different wavelengths diffract at different angles when encountering a change in media, such as air to glass, at an angle. Isaac Newton noted this in his study of light and prisms.
Any incident ray traveling parallel to the principal axis of a converging lens will refract through the lens and travel through the focal point on the opposite side of the lens.Any incident ray traveling through the focal point on the way to the lens will refract through the lens and travel parallel to the principal axis.An incident ray that passes through the center of the lens will in effect continue in the same direction that it had when it entered the lens.
A lens brings diverging light rays to parallel tracks by refracting the light rays as they pass through the lens. The shape of the lens causes the light rays to converge and then diverge again, ultimately causing them to travel in parallel paths.
Light traveling through a lens appears to converge or diverge depending on the shape of the lens. In a converging lens, the light rays come together at a focal point after passing through the lens, whereas in a diverging lens, the light rays spread out. The path of light through a lens can be visualized using ray diagrams.
Light goes in the lens, refraction occurs, and the light exits the lens.
The term for an image through which light does not really travel is "virtual image." These images are formed by the apparent intersection of light rays that appear to come from a point behind a mirror or lens, but do not actually pass through.
Straight. Gravity bends light. It can act like a lens
