It is the ability of a lens to converge or diverge a ray of light.
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.
the objective lens has the power of that lens inscribed on it
The Power
See the link below for the formula of lens power.
define the term centre of curvature
A lower power lens tells its name in the name. It is a lens in a microscope that has the lowest power, or only magnifies the object you are looking at a little.
Which of the following is a correct procedure for the operation of a microscope? First, put the specimen into focus using a low power lens, then switch to a lower power lens if needed.Remove and add slides while the high power lens is selected.First, put the specimen into focus using a low power lens, then switch to a higher power lens if needed.Use the fine focus knob with the low power lens and use the coarse focus knob with the high power lens
The power of a lens is 1/focal length (measured in meters).
low power objective lens
low power
A microscope should be stored in low power objective lens because the lens can scratch against the lens.
The low power objective lens is usually a 10x lens and it is used to orient the specimen and get it focused before switching to a higher power lens.
