Atmospheric carbon dioxide strongly absorbs light in the
To determine the frequency range that corresponds to and the region of the electromagnetic spectrum.
Answer to Problem 61A
The frequency range is (300GHz - 3×1013Hz). It is in the Microwave/infrared region.
Explanation of Solution
Given data:
Light range (λ ) = 12.5 µm - 18 µm = 1.25×10-5 m − 1.8×10-5m.
Formula used:
Calculation:
We know that, the speed of light c =3×108m/s.
Substituting the values in the equation of frequency (f) is,
= 2.4×1013Hz.
And,
Hz.
= 1.6×1013Hz.
Therefore, the range is 300GHz - 3×1013Hz from obtained values corresponds to the electromagnetic spectrum.
Conclusion:
The range of frequency 300GHz - 3×1013Hz, falls under the microwave/infrared region on the electromagnetic spectrum.
