Question
The second is defined as the time it takes for $9,192,631,770$ wavelengths of a certain transition of the cesium- 133 atom to pass a fixed point. What is the frequency of this electromagnetic radiation? What is the wavelength?
Step 1
The frequency is the number of cycles (or wavelengths) that pass a fixed point per unit of time. Since we know that 9,192,631,770 wavelengths pass a fixed point in 1 second, the frequency is: Frequency (f) = 9,192,631,770 cycles/second (Hz) Now, we need to find Show more…

The SI unit of time is the second, which is defined as 9,192,631,770 cycles of radiation associated with a certain emission process in the cesium atom. Calculate the wavelength of this radiation (to three significant figures). In which region of the electromagnetic spectrum is this wavelength found?
The meter was defined in 1963 as the length equal to 1,650,763.73 wavelengths of the orange-red radiation emitted by the krypton-86 atom (the meter has since been redefined). What is the wavelength of this transition? What is the frequency?
