Answer:
Infrared
Explanation:
To calculate the wavelength if the electromagnetic radiation, we must use the following formula:
c = f × λ
where c is the speed of the wave (in this case it's the speed of light, which is 3 ×
m/s) , f is the frequency and λ is the wavelength.
Using this formula, all we have to do is plug in our values and rearrange for the answer:
c = f × λ
3 ×
= 5.00 x
Hz × λ
λ = 3 ×
/5.00 x
λ = 6.00 ×
m = 6.00 ×
nm
Now that we know the wavelength we can figure out which kind of electromagnetic radiation this is.
6.00 ×
nm falls in the range of infrared radiation. We know this either from memorizing the values of the wavelengths or looking up a reference.
