What else can I help you with?
Can a lens have it's optical centre outside the lens?
No, the optical center of a lens is always located within the lens itself. It is the point from which light rays appear to converge and is used as a reference point for optical calculations.
A lens of glass is immersed in water. What will happen to its power?
The power of a lens depends on the differences in the refractive indices of the environment and the lens material. A glass lens immersed in water will loose power (a positive lens will focus at a greater distance). (This is for normal glass with refractive index greater than water - there could be glasses with refractive index less than water in which case the lens would gain power)
What happen if the microscope lens touch the slide?
1. The lens could break the slide or slip 2. The lens could make contact with a fluid on the slide, and suck the fluid up around the edges of the lens. It could even damage the lens. In any case, it would take a lot of bucks to have the microscope repaired.
If a microscope had a power of magnification of 200x what would the power of the objective lens be if the eyepiece lens is 10x?
The total magnification of a microscope is calculated by multiplying the power of the objective lens by the power of the eyepiece lens. Given a total magnification of 200x and an eyepiece lens power of 10x, the power of the objective lens would be 200x/10x = 20x.
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.
When did Battle of Lens happen?
Battle of Lens happened on 1648-08-20.
To magnify an object would you use a convex lens or a concave lens?
You would use a convex lens.
What would happen to a person's vision if the eye's lens as unable to change shape?
Then the person wouldn't be able to see very well.
What type of lens would you use to magnify an object?
You would use a convex lens.

What type of lens would you use to examine a tiny insect?
convex lens

What lens would you use to shoot a models head outside in overcast weather?
i would rather use a convex lens
What kind of lens which diverges light rays?
Concave lens would diverge the rays.

What is the magnification of a 30 times lens?
A 30 times lens would magnify an object by 30 times its original size when viewed through the lens.
