Nope.. because mirror doesn't forms images by following laws of refraction they follows laws of reflection.
consider a plane immersed in the liquid, obviously beam of light will bend(refraction of the liquid) but when it reaches the surface it simply reflects back(laws of reflection) thus the condition will be again satisfied Angle i=Angle r.
only in case of lens it changes(By lens maker's formula)
No, the focal length of a mirror does not change when the object distance changes. The focal length of a mirror is a fixed property of the mirror itself. Changing the object distance will affect the position and size of the image formed by the mirror, but not the focal length.
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
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 objects size is not going to change. The image size, however, would.
yes
The focal length of a concave mirror is a function of its radius only (a geometry function), not of its material nor the material surrounding it. To change the focal length you wound have to alter it physically. Keep in mind that the light or whatever is being focused does not make a media change. It never enters the mirror media. It is always in the surround media, whatever that is, so Snell's law does not apply here.
The focal length remains the same because only refraction is affected by the different media. Reflection does not depend on the media.
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.
When an object is placed closer to a concave mirror than its focal length, the image formed is virtual, upright, and magnified. The image is located behind the mirror, and the rays of light appear to diverge from a point behind the mirror rather than converging at a real focal point.
Excellent question. The answer is actually yes! According to the lens makers formula, it will change based on the refractive index of the material of the concave mirror wrt the medium. Google Lens makers formula for better understanding! NO! the focal length of the mirror will not change if it would be a lens then the focal length would change. The lens maker's formula is for Lenses only!
The focal length of the telescope's mirror can be calculated using the formula: Telescope focal length = Eyepiece focal length × Magnification = 26 mm × 70x = 1820 mm Therefore, the focal length of the telescope's mirror would be 1820 mm.
A concave mirror can give a virtual and larger image than the object when the object is placed within the focal length of the mirror. When the object is placed beyond the focal point, a real, inverted, smaller image is formed.
