When a ray of light passing through a point in a lens does not undergo deviation?
When it passes through optical centre.
How does light behave as it passes through a concave lens and a convex lens?
It slows the light down
What happens to light after it passes through a converging lens and after it passes through a diverging lens?
becomes more converging
What will happen to the parallel raysof light after falling on a convex lens and passed through the lens?
A parallel beam of light coming from an infinite source when passed through a convex lens such that the refractive index of medium is less than the refractive index of lens the light will suffer deviation and the rays will converge at a point called focus of the lens on the opposite side where the rays have been coming. The image will be highly diminished as all the rays converge at a point.
Difference between focal point and focal length?
The focal point is the point where light converges after it passes through a concave lens. The focal length is the distance of the focal point to the lens. Same for a convex lens, except that the focal point is the imaginary point from where light deflected from lens seems to have emerged.

What happens when light passes through lens?
The light refracts or bend .
After light passes through the specimen it enters what next lens system?
objective lens system
When light passes through a lens what do you call the result?
Refraction
Is light bends when it passes through a convex lens?
No it do not bend.
Aperture?
Opening of the lens diaphragm through which light passes
Does a lens heat up when light passes through it?
Typically a lens will heat up as light passes through it. No lens is perfectly transparent so some of the light energy will be reflected and some of it will be absorbed. The part that is absorbed will manifest as an increase in the temperature of the lens. The closer the lens is to being perfectly transparent to the wavelengths of the light passing through, the less it will heat up.
What happens when light passes through a concave lens and a convex lens?
The light is delayed longer by the thicker part of the lens than by the thinner part of the lens. This results in the following:convex lens, light rays bend towards the axis of the lensconcave lens, light rays bend away from the axis of the lens
What happens when light passes through a cylindrical lens?
sh@@ happens
Parts through which light passes as it enters the eye?
As light enters the eye, it passes through the cornea and the lens and is eventually focused onto the retina.
