Definition of lens holder?
It holds the lense its kinda obvious :)
What is the Definition of working distance in microscopy?
The working distance is the distance between the cover slip and the bottom of the housing fo the objective lens.
What is an exaggerated thoracic curvature?
Kyphosis is an exaggerated outward curvature of the spine, which causes hunching of the back. It can occur at any age but is usually prominent in older women.
What is the definition of fully forward control in automobile chassis?
FORWARD-CONTROL VEHICLE - a motor vehicle in which the centre of the steering wheel is in the forward quarter of the vehicle's 'Total Length'
Define principal focus and principal aris?
principal focus is the ray which diverge at a point on the other side of the lensPrincipal Axis lens have two centre of culvature,the line passing through them and joining these centres is called principal axis.
How does a focal length change as a convex lens becomes flatter?
d focal lenght increases due to increases in the distance between centre of curvature and the centre of the convex lens on the principal axis
What is definition for the centre of curvature of a spherical mirror?
It is the center of the imaginary sphere to which the mirror belongs.
How lens power change with curvature of lens surface?
The lens power increases as the curvature of the lens surface becomes steeper. A lens with a larger radius of curvature will have a lower power, while a lens with a smaller radius of curvature will have a higher power. This relationship is described by the lensmaker's equation, which relates the power of a lens to the refractive index of the lens material and the radii of curvature of its surfaces.
What is the center of curvature of the mirror?
the centre of sphere is known as centre of curvature
What is the difference between Radius of curvature and centre of curvature?
the center of curvature is the ORIGIN of the radius of curvature
What is a defective curvature of the cornea and lens of the eye?
the defective curvature on the cornea or lens is called Astigmatism
Does the lens in the eye have fixed curvature?
The curvature lens of an eye is a transparent structure of eye which works to refract light to be focused on retina. The curvature adjusts according to angle and view therefore it is not fixed.
What objective lens is the longest?
The lens with the greatest (positive) curvature. The lens with the highest diopter.
The curvature of an eye's convex lens is change by?
Muceles
Where will the image form when you place an object on the principal axis of a concave mirror at a point between focus and centre of curvature?
If the object is placed on the principal axis of a concave mirror at a point between the focus and centre of curvature the image will form beyond the centre of curvature
Is the image larger or smaller through a convex lens?
both according to the position of the image in front of the lensif placed in infiniity or beyond the centre of curvature the image will be small if placed between centre of curvatureand pole the image will be bigger in size
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
