What is the number of pole of mirror?
The center of the spherical reflecting surface of the mirror is called the pole of the mirror.
What is a flat mirror called?
If the mirror is convex (bulges out, like a ball), objects in the mirror will appear smaller or further away, but the mirror will show a larger scene (called a wider field of view), including objects that a flat mirror would miss around the edges. If the mirror is concave (like the inside of a dish), it can magnify images or focus light onto a small spot. A large concave mirror can focus sunlight and produce a very hot spot.
What is a reflecting telescope that used a secondary mirror to send light through a hole in the primary mirror is called?
It is called a Cassegrain. The small convex subreflector is a hyperboloid with one focus at the focus of the main mirror, and the other focus just behind the main mirror where the eyepiece is.
The type of mirror that resembles the inner surface of a spoon is called?
A mirror that bows inward is called concave. The opposite, a mirror that bows outward would be called convex. Convex mirrors are used to to increase the field of view around corners and blind spots. Concave mirror serve no purpose other than novelty (making you appear thin or odd)
What is a reflecting telescope that uses a secondary mirror to send light through a hole in the primary mirror called?
That is called a Cassegrain. The main mirror is a paraboloid which focusses the light from a star down to a point, then the secondary small mirror is a hyperboloid with one focus that coincides with the focus of the main mirror, and the other focus is behind the main mirror, where the eyepiece is. This arrangement is common in radio telescopes as a way of reducing radio noise picked up from the 'hot' ground which is at approximately 260 degrees Kelvin or more.
What is the center of spherical mirror?
The geometric centre of a spherical mirror is called its pole. The centre of the hollow sphere for which the mirror is a part, is called the centre of curvature. The line joining the centre of curvature and the pole is the principal axis. A light ray incident on a spherical mirror, after reflection appears to pass through the principal focus in the case of a convex mirror and passes through the focus in the case of concave mirror. The diameter of the spherical mirror gives the measure of its aperture
What is the center of curvature of the mirror?
the centre of sphere is known as centre of curvature
Where will the image form when you place an object on the principal axis of a concave mirror at a point between focus and centre of curvature?
If the object is placed on the principal axis of a concave mirror at a point between the focus and centre of curvature the image will form beyond the centre of curvature
What is the ratio of focal length of a spherical mirror to its radius curvature?
The focal point of a convex mirror lies on the same side as the centre of curvature and is at a distance of half the radius of curvature from the optical centre.
What is definition for the centre of curvature of a spherical mirror?
It is the center of the imaginary sphere to which the mirror belongs.
What is the difference of a concave mirror to a convex?
Concave mirror* its reflecting surface is curved inwards*it can form both real and virtual images*the centre of curvature and the focus lies in front of the mirror*it can form both enlarged and diminished imagesConvex mirror* its reflecting surface is curved outwards*it can form only virtual images*the centre of curvature and the focus lies behind the mirror*it can form only diminished images
Examples of concave and convex mirrors?
Convex means rounded or curved like the exterior of a circle or sphere. Also called as fish eye or diverging mirror. The mirror coating of the concave mirror is on the outside of the spherical surface. In concave mirrors, the center of curvature and the reflecting surface fall on the same side of the mirror.
What are spherical mirrors?
The most curved mirrors are spherical mirrors. The centre of curved surface is called center of curvature. There are two kinds of spherical mirrors. Concave and convex mirror.
What is radius of curvature?
The radius of the sphere of which a lens surface or curved mirror forms a part is called the radius of curvature.
How do you derive relation between focal length and radius of curvature of convex mirror?
the curvature mirror the emage of the mirror is virtual
What is the center of curvature of a mirror?
A plane mirror is not curved so it does not have a center of curvature. Or if you want to be mathematically correct, you could say that it's center of curvature is at an infinite distance from the mirror.
The relation between focal length and radius of curvature of spherical mirror is?
The focal length of a convex mirror is half of its radius of curvature.
