Yes , because when lens is deeped in water its R.I changes & hence focal length is increased

How does change in the thickness of lens change the focal length of lens?
Not at all. The focal length is determined by the curvature of the surfaces.
What is the ability of the eye to change it's focal length?
accomodation
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!
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.
What is the relation of focal length of eye with its curvature?
More the curvature of the eye lens, lesser the focal length is. Lesser the curvature, greater the focal length is
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.

What happens to focal length when convex lens is cut horizontally?
no change
Will focal length of concave mirror change when kept in water?
yes

What happens if you decrease a telescopes eyepiece focal length?
The magnification of the telescope image is(focal length of the objective) divided by (focal length of the eyepiece).The focal length of the objective is fixed.Decreasing the focal length of the eyepiece increases the magnification of the image.(But it also makes the image dimmer.)

What would be the effect on magnification to increase the focal length of microscope and telescope?
The focal length of a telescope is directly related to the magnification in that the longer the focal length, the more magnification you get from the telsceope. How the focal length of a telescope relates to the length of the telescope itself depends on the design of the telescope. In a refracting telescope, the focal length is approximately the length of the telescope. In a reflecting telescope, the focal length is roughly two time the length of the telescope.
If the primary mirror of a telescope have a focal length of 225 centimeters and the eyepiece has a focal length of 7.5 millimeters then what is the magnifying power of the telescope?
The magnifying power of a telescope is the focal length of the scope in millimeters, divided by the focal length of the eyepiece in millimeters. Focal length of scope: 225cm=2250mm Focal length of eyepiece: 7.5mm 2250/7.5= 300X
