The unit for the power of a lens is measured in diopters (D). The power of a lens is a measure of the lens's ability to focus light, with positive values indicating convergence (for lenses that focus light) and negative values indicating divergence (for lenses that spread out light).
The optical power of a concave lens is negative, as it causes light rays to diverge when passing through the lens. The unit of optical power is diopters (D), and it is the reciprocal of the focal length in meters.
A concave lens is called a negative lens because it causes light rays passing through it to diverge, or spread out. This is in contrast to a convex lens, which converges light rays and is called a positive lens. The negative or positive designation refers to the effect the lens has on the light rays.
The unit of measurement for lens refractive power is diopters (D), which indicates the strength of the lens to bend light. Positive values indicate converging power (for correcting farsightedness), while negative values indicate diverging power (for correcting nearsightedness).
If the lens equation yields a negative image distance, then the image is a virtual image on the same side of the lens as the object. If it yields a negative focal length, then the lens is a diverging lens rather than the converging lens in the illustration.
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 total magnification of a microscope is calculated by multiplying the power of the objective lens by the power of the eyepiece lens. Given a total magnification of 200x and an eyepiece lens power of 10x, the power of the objective lens would be 200x/10x = 20x.
The power of a lens is inversely proportional to its thickness. Thicker lenses have a higher power, while thinner lenses have a lower power. This relationship is determined by the curvature of the lens surfaces and the material it is made of.
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.
The power of a lens is 1/focal length (measured in meters).
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
