The focal length of a lens can be calculated by measuring the distance between the lens and the image plane when an object far away is in focus. This distance is the focal length of the lens. Alternatively, the focal length can be found using the lens maker's formula: 1/f = (n-1) * (1/R1 - 1/R2), where f is the focal length, n is the refractive index of the lens material, and R1 and R2 are the radii of curvature of the two lens surfaces.

How do you calculate the power of magnificaiton?
The power of magnification is calculated by dividing the focal length of the objective lens by the focal length of the eyepiece lens in a microscope or telescope. The formula is: Magnification = Focal Length of Objective Lens / Focal Length of Eyepiece Lens. For example, if the objective lens has a focal length of 10 mm and the eyepiece lens has a focal length of 25 mm, the magnification would be 10/25 = 0.4x. Additionally, in microscopy, total magnification can also be determined by multiplying the magnification of the objective lens by that of the eyepiece lens.

Divide the focal length of the objective lens by the focal length of the eyepiece.

Does a diverging lens have a focal length?
Yes, a diverging lens does have a focal length. The focal length of a diverging lens is negative, as the light rays diverge after passing through the lens.
What is the lens maker's formula and how is it used to calculate the focal length of a lens?
The lens maker's formula is a mathematical equation used to calculate the focal length of a lens based on its refractive index and the radii of curvature of its surfaces. It is expressed as: 1/f (n - 1) (1/R1 - 1/R2) Where: f focal length of the lens n refractive index of the lens material R1 radius of curvature of the first lens surface R2 radius of curvature of the second lens surface By plugging in the values for n, R1, and R2 into the formula, one can determine the focal length of the lens.
