A refracting telescope is a type of optical telescope. It was used in astronomical telescopes and spy glasses. Objective lens are used to produce the image.
A reflecting telescope has both an eyepiece lens and a mirror. Light enters the telescope and is reflected off the primary mirror to a secondary mirror, which then directs the light to the eyepiece where it is magnified for viewing.
Eyepiece, Primary Mirror, Secondary Mirror, Prime Focus.
The resolution is directly proportional to the diameter of the main mirror or lens. For instance, twice the diameter means twice the resolution.
The objective lens or mirror is the part of a telescope that focuses the incoming light. This lens or mirror gathers the light from a distant object and brings it to a focus at a specific point in the telescope where it can be magnified for viewing.
usualy concave mirror.
a lens you can see through and a mirror reflects
Lens, light, mirror
we can use convex lens(having tapered ends) for that. but the magnifying capability depends on the power the lens. A magnifying glass works by creating a magnified virtual image of an object behind the lens. The distance between the lens and the object must be shorter than the focal lenght of the lens for this to occur. Otherwise, the image appears smaller and inverted, and can be used to project images onto surfaces.
concave lens will form exact mirror image.
Concave and convex can refer the types of lenses used to treat refractive errors in the eyes. Concave is another word for myopic lens and convex is another name for a hyperopic lens also known as nearsighted and farsighted respectively
The focus is the point at which light rays converge after passing through a lens or reflecting off a mirror. For a concave mirror or converging lens, the focus is in front of the mirror/lens. For a convex mirror or diverging lens, the focus is behind the mirror/lens.

A Condenser Lens is a device made up of a series of lenses and sometimes a mirror, that is used to gather and 'focus' light to direct it onto an object through a different projection lens.
a lens will focus the light to a point or will disperse it(concave or convex lens) same as with a mirror, tho lens have a differnce, they are transparent and will let the light rays pass through themand form a real image behind the lens, while a mirror cannot.
No, the normal is drawn perpendicular to the surface of the mirror or lens at the point where light rays strike. It is used to determine the angle of incidence and reflection or refraction.
A concave mirror is used in a solar cooker to concentrate sunlight onto a central point, where the cooking vessel is placed. This focusing of sunlight helps to increase the temperature inside the solar cooker for cooking food.
