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.
Will focal length of mirror change on changing the object distance?
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.
What will happen to the focal length of a lens if it is cut into half vertically?
When the lens is cut vertically then the focal length of the lens will increase.the focal length will become approx double.
How does change in the thickness of lens change the focal length of lens?
Increasing the thickness of the lens generally decreases the focal length, while decreasing the thickness increases the focal length. This is due to the way light rays bend and converge or diverge as they pass through different thicknesses of the lens. The relationship between lens thickness and focal length is determined by the lens's refractive index and curvature.
Why does the focal length of a concave mirror not change when held in water?
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.
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 the focal length of mirror changes if it is immersed in liquid?
No. Light behaves the same way in the liquid as it would in the air (as far as reflection is concerned, so the focal length of a mirror would not change if it were immersed in liquid.
Will focal length of mirror change on changing the object distance?
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.
How can I change the focal length on an Android device?
To change the focal length on an Android device, you can use the zoom feature on the camera app. Simply open the camera app, locate the zoom option, and adjust the focal length by either pinching the screen or using the zoom slider. This will allow you to zoom in or out and change the focal length of the camera.
What will happen to the focal length of a lens if it is cut into half vertically?
When the lens is cut vertically then the focal length of the lens will increase.the focal length will become approx double.
How does change in the thickness of lens change the focal length of lens?
Increasing the thickness of the lens generally decreases the focal length, while decreasing the thickness increases the focal length. This is due to the way light rays bend and converge or diverge as they pass through different thicknesses of the lens. The relationship between lens thickness and focal length is determined by the lens's refractive index and curvature.
Will focal length of concave mirror change when kept in water?
yes
What happens to focal length when convex lens is cut horizontally?
no change
What is the difference between zoom and focal length in photography?
Zoom in photography refers to the ability to change the focal length of a lens to make the subject appear closer or farther away. Focal length, on the other hand, is the distance between the lens and the image sensor, which determines the angle of view and magnification of the image. In simpler terms, zoom is the act of adjusting the focal length to change the size of the subject in the frame.
Why does the focal length of a concave mirror not change when held in water?

What is the relationship between field of view (FOV) and focal length in a focal length calculator?
In a focal length calculator, the field of view (FOV) and focal length have an inverse relationship. This means that as the focal length increases, the field of view decreases, and vice versa.
Length of a lens is the distance from the center of the lens to its principal focus?
It is called the focal length. It is equal to 1/2 times r, and is positive on concave mirrors and negative on convex mirrors.
