Does the focal length of a spherical mirror change if immersed in water?
No, the focal length of a spherical mirror does not change when immersed in water. The change in medium from air to water affects the refractive index and the speed of light, but it does not affect the focal length of the mirror.
The relation between focal length and radius of curvature of spherical mirror is?
The relation between focal length (f), radius of curvature (R), and the focal point of a spherical mirror can be described by the mirror equation: 1/f = 1/R + 1/R'. The focal length is half the radius of curvature, so f = R/2.
How is the focal length of a spherical mirror affected when the wavelength of light used is increased?
The focal length of a spherical mirror is not affected by the wavelength of light used. It is determined by the mirror's radius of curvature and refractive index of the surrounding medium. The wavelength of light only influences the diffraction effects, not the focal length.
What is definition for the centre of curvature of a spherical mirror?
The center of curvature of a spherical mirror is the point at the center of the sphere from which the mirror is a part. It is located at a distance equal to the radius of the sphere. The center of curvature is an important point for determining the focal length and the magnification of the mirror.
Is plane mirror a spherical mirror why?
No, a plane mirror is not a spherical mirror. A plane mirror has a flat reflective surface, while a spherical mirror has a curved reflective surface. The shape of the mirror affects the way light is reflected, with spherical mirrors causing light rays to converge or diverge depending on their curvature.
Does the focal length of a spherical mirror change if immersed in water?
No, the focal length of a spherical mirror does not change when immersed in water. The change in medium from air to water affects the refractive index and the speed of light, but it does not affect the focal length of the mirror.

Does a broken piece of a spherical mirror works as another spherical mirror?
Yes, spherical mirror is the part of a spherical reflecting surface.when it is broken the broken piece is also the part of the spherical reflecting surface.
Is plane mirror a spherical mirror why?
No, a plane mirror is not a spherical mirror. A plane mirror has a flat reflective surface, while a spherical mirror has a curved reflective surface. The shape of the mirror affects the way light is reflected, with spherical mirrors causing light rays to converge or diverge depending on their curvature.
is plane mirror is a spherical mirror why?
plane mirror is never a spherical mirror,spherical mirrors are made up by cutting the part of the sherical balls and then polishing them.while the plane mirror is just a sheet of polished glass
When was Still Life with Spherical Mirror created?
"Still Life with Spherical Mirror" was created by M.C. Escher in 1934.
What are uses of spherical mirror?
that mirror is mystery
What is mirror formula .explain magnification in case of spherical mirror?
The mirror formula is a relationship that connects the object distance (u), image distance (v), and focal length (f) of a spherical mirror: 1/f = 1/v + 1/u. Magnification in the case of a spherical mirror is given by the ratio of the height of the image to the height of the object: M = -v/u. The negative sign indicates that the image is inverted relative to the object.
Does the focal length of a spherical mirror or lens change when placed under water?
No, the focal length of a spherical mirror or lens does not change when placed under water. However, the refractive index of water can affect the behavior of light passing through the mirror or lens. The light will experience refraction at the air-water interface, but the focal length of the mirror or lens itself remains constant.
What is the center of spherical mirror is called?
The center of a spherical mirror is called the vertex. This is the point where the principal axis intersects the mirror's surface.
