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 3 sig figs). in which region of the electromagnetic spectrum is the wavelength found?

Answer :  The wavelength of this radiation is, and in microwave region, the electromagnetic spectrum the wavelength is found.

Explanation : Given,

Frequency of radiation =

Formula used :

where,

= frequency of radiation

= wavelength of radiation

c = speed of light =

Now put all the given values in the above formula, we get:

Thus, the wavelength of this radiation is, and in microwave region, the electromagnetic spectrum the wavelength is found.

the answer would be c
