A lens is formed from a plastic material that has an index of refraction of 1.59 . If the radius of curvature of one surface is 1.15 m and the radius of curvature of the other surface is 1.80 m , use the lensmaker's equation to calculate the magnitude of the focal length | f | and the power | P | of the lens.

a) 5.39 m

b) 0.18 m^-1

Explanation:

The focal length of this kind of optical system is given by:

you replace the values of the parameters in order to find the focal length:

hence, the magnitude of the focal length is 5.39m

The power of the lens is:

the power of the lens is 0.18 m^-1

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
