Answer:
a) The frequency is 3.191x10^11.
b) The type of radiation is microwave radiation.
c) The energy of one quantum of this radiation amounts to 1.32x10^-3ev.
Explanation:
For further details and calculations, please refer to the image below.
In terms of light energy, a higher frequency corresponds to increased energy within the light.
We establish that frequency is essentially the inverse of wavelength:
frequency = 1 / wavelength
Calculating frequencies:
f UVA = 1/320 to 1/400
f UVA = 0.0031 to 0.0025
f UVB = 1/290 to 1/320
f UVB = 0.0034 to 0.0031
Since UVB occupies a higher frequency range, it consequently possesses greater energy than UVA.
