Acertain part of the electromagnetic spectrum ranges from 200 nm to 400 nm. what is the highest frequency associated with this portion of the spectrum? (c = 3.00 × 108 m/s)

The lowest and highest wavelengths of this part of the electromagnetic spectrum are:



The frequency and the wavelenght of an electromagnetic wave are related by

where c is the speed of light and f the frequency. By using this equation, we can find the frequencies that corresponds to the lowest and highest wavelengths of this part of the spectrum:



So, the highest frequency associated with this part of the spectrum is the one corresponding to the lowest wavelength:

the simple machine has three main features. they are:

loadfulcrumeffort

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
