A hyperbolic lens has a unique shape that can focus light in a specific way, allowing for applications in fields such as astronomy, microscopy, and telecommunications. Its properties include the ability to correct spherical aberrations and produce high-resolution images.
A positive meniscus lens has a curved shape that causes light to converge, making it useful for focusing and magnifying images. Its unique optical properties include reducing spherical aberration and increasing depth of field. Applications of a positive meniscus lens include camera lenses, microscopes, and telescopes.
In an experiment using a liquid lens, the convex lens helps to focus the light passing through the liquid lens. This allows for the manipulation of the shape of the liquid lens which can change its focal length. By adjusting the curvature of the liquid lens and using the convex lens, the overall optical properties of the system can be controlled for various applications.
Lenses can be made from various materials such as glass, plastic, and crystals. The choice of material depends on the desired properties of the lens, such as clarity, refractive index, and durability. Each material has its own advantages and suitability for different applications.
The lens maker formula is a mathematical equation used to calculate the focal length of a lens based on its refractive index and the radii of curvature of its surfaces. It is expressed as: 1/f (n - 1) (1/R1 - 1/R2) Where: f is the focal length of the lens n is the refractive index of the lens material R1 is the radius of curvature of the first lens surface R2 is the radius of curvature of the second lens surface By plugging in the values for n, R1, and R2 into the formula, you can calculate the focal length of the lens. This formula is essential for lens designers and manufacturers to ensure that lenses have the desired optical properties for various applications.
Cornu's fringes are hyperbolic because they are formed due to the interference of light waves that are not perfectly spherical when they meet at an angle. Newton's rings are circular because they are formed by the interference of light waves that are spherical in shape due to reflection between a flat glass surface and a convex lens.

some old enlarge lens-boards just had aplain hole in them so you needed the threaded ring to fix the lens in to the board
Convex.
It depends on the orientation and whether the lenses are parabolic or hyperbolic. Parabolic lenses aligned perfectly in front of each other would increase spread and diffuse light if you fired light straight into the parabola. Hyperbolas would continually concentrate light until it crossed over then would diffuse unless you put another lens somewhere along the line. The cross over would the the focal point and the distance between lens and focal length.
