What is the differebetween a lens and a mirror?
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.
Does the focal length of a spherical mirror or lens change when placed under water?
i do not think so because a mirror an a lens is two same things except that mirrors can reflect the water and the lens may refract or bend the water so that can change the focal length between the mirror and the lens
Which lens will form exact mirror image?
concave lens will form exact mirror image.
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 is the difference between concave lens and the concave mirror?
Not much except concave mirror reflects and concentrate the light and lens let trough and distorts the light "concave -the inner surface of a sphere." defines the shape of the lens or mirror
Why does the focal length of a mirror not depend on the mirror material when the focal length of a lens does depend on the lens material?
The focal length for a mirror is determined by the law of reflection from the mirror surface. This law is not governed by the material that the mirror is made by. This means that the focal length depends only on the radius and curvature. Conversely, the focal length of a lens depends on the indices of refraction of the lens meterial and the surrounding medium.
The light-gathering power of a telescope varies with the of the diameter of the lens or mirror?
Yes, that is correct. A greater main mirror, or main lens, will gather more light.Yes, that is correct. A greater main mirror, or main lens, will gather more light.Yes, that is correct. A greater main mirror, or main lens, will gather more light.Yes, that is correct. A greater main mirror, or main lens, will gather more light.
Why does a reflecting telescope have no chromatic aberration?
There's no aberration with the main MIRROR of the telescope, because light doesn't go through the mirror. A reflecting telescope will have SOME chromatic aberration, because every reflecting telescope has at least one refracting lens; the eyepiece. Light goes THROUGH that lens, and light passing through the glass lens will generate some chromatic aberration.
Which lens and which mirror forms a visible focal point?
A concave lens and a convex lens are what you're looking for. / | ∙ \
Where can I find a replacement lens for the mirror of my 2004 Expedition?
So far I can find only entire mirror assemblies...I only need the lens.
What is a mirror or lens that is curved inward is?
concave
A mirror or lens that curves outward is?
convex
