Answer:
2.3)X10^13-Hz
Explanation:
What’s the frequency of radiation that has a wavelength of 13 um, about the size of bacterium?
a micro meter is 10^-6 meter
frequency of light times wavelength = c the speed of light 3X10^8 M/sec
so
frequency times 13 X10^-6 =3X10^8 M/
so
FR3EQUENCY = 3X10^8/13X10-6
=(30/13)10^13 =2.3)X10^13-Hz
7 X
6
