The diagram below shows the wavelengths and frequencies for the various regions of the electromagnetic spectrum.

which of the following is true about the frequencies of electromagnetic radiation?
a. x-rays have lower frequencies than infrared waves.
b.
gamma rays have lower frequencies than ultraviolet waves.
c.
ultraviolet waves have higher frequencies than radio waves.
d.
radio waves have higher frequencies than x-rays.

option C

Explanation:

Actually the order of frequencies for various regions of the electromagnetic spectrum is

So from this order of frequencies Gamma rays has the largest frequency and Radio waves has the least frequency

For the order of wavelengths, it is just opposite to the order of frequencies because from the formula c=(wavelength of the light)×(frequency of the light)

As the wavelength of the radio waves is more, it actually means that radio waves can travel a large distance and as the frequency of the Gamma rays is more it can penetrate easily through any body  

what is the question?

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools
