Will focal length of concave mirror change when kept in water?
yes
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.
A concave mirror and a convex lens are held in waterwhat changes if any do you expect in their focal length?
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!
Why the focal length of concave mirror changes in water?
I don't think so. The focal length would remain the same. It mainly depends on the radius of curvature of the mirror.
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.
How focal length of a lens change when apparatus immersed in water?
The focal length of a lens decreases when it is immersed in water due to the change in the refractive index of the medium. This change causes the light rays passing through the lens to bend differently, altering the focal point of the lens.
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
How do you find the new focal length when the lence is put in to the water?
to find the new focal length when the lens is put into water it becomes the 4 times the focal length in air.
Will the focal length of a lens change when put in water?
A careful reading of the question raises the uncomfortable suspicion that it might be very difficult to put the focal length in water. However, it's quite possible to put the lens itself in water. When that's done, it's quite likely that the lens's focal length has changed. The refractive indexes of both materials ... the substance of which the lens is made and the medium around it ... are both involved in determining its focal length.
What is the focal length of a mirror when it is placed in water with respect to air?
The focal length remains the same because only refraction is affected by the different media. Reflection does not depend on the media.
Why does a concave meniscus form when water is in a graduated cylinder?
A concave meniscus forms in a graduated cylinder with water due to adhesive forces between the water molecules and the walls of the cylinder. This causes the water to cling to the walls, resulting in a concave shape.
Why concave mirror is used in solar cooker?
A concave mirror is used in a solar cooker to focus sunlight at a single point, increasing the intensity of the heat produced. This concentrated heat is then used for cooking food or heating water efficiently. The shape of the concave mirror allows for better collection and concentration of sunlight compared to a flat mirror.
