Magnifying power of simple microscope can be increased by?
decreasing focal length of the lens
Which lens has a greater power convex lens of focal length 10 cm or a convex lens of focal length 20cm?
Power is inversely related to the focal length. So convex lens of focal length 20 cm has less power compared to that having focal length 10 cm
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.
The relation between focal length and radius of curvature of spherical mirror is?
The focal length of a convex mirror is half of its radius of curvature.
What is the power of a convex lens with 10cm focal length?
1.0 diopters
Magnifying power of simple microscope can be increased by?
decreasing focal length of the lens
Why the study was under taken of focal length of a convex lens by graphical method?
to determine the focal length of a convex mirror.
What is the difference of compound microscope from a simple microscope?
compound microscope consists of 2 lences of short focal length & short aurpature .
Which lens has a greater power convex lens of focal length 10 cm or a convex lens of focal length 20cm?
Power is inversely related to the focal length. So convex lens of focal length 20 cm has less power compared to that having focal length 10 cm
What is the focal length of the convex lens?
The distance from the centre of the lens to the focal point.
What happens to the focal length of convex lens when convex lens is cutted vertically along the optic center?
its focal lenght becomes 2f
Construction of the simple microscope?
A simple microscope consists of a single convex lens with a short focal length. This lens is typically mounted on a frame or stand that holds it in place and allows for adjustment. The object to be viewed is placed in front of the lens and the viewer looks through the lens to see the magnified image. The magnification is determined by the focal length of the lens, which can range from 5x to 250x. The resolution of the microscope is determined by the quality of the lens. The frame or stand is typically made of metal or plastic and may include a focusing mechanism.

The relation between focal length and radius of curvature of spherical mirror is?
The focal length of a convex mirror is half of its radius of curvature.
What is the power of a convex lens with 10cm focal length?
1.0 diopters
What happens to focal length when convex lens is cut horizontally?
no change
When do convex lens produce real image?
When the object length is less than the focal length
