(a) (d) (c) (b)
To arrange the given microwave bands in descending order of their frequencies, we need to understand the frequency ranges associated with each of the microwave bands mentioned in the question. Typically, the frequency ranges for these bands are as follows:
- Ka Band: 26.5 GHz to 40 GHz
- X Band: 8 GHz to 12 GHz
- C Band: 4 GHz to 8 GHz
- L Band: 1 GHz to 2 GHz
Now, let's arrange these bands in descending order of frequency:
- The Ka Band has the highest frequency range (26.5 GHz to 40 GHz).
- Next, the X Band follows with frequencies ranging from 8 GHz to 12 GHz.
- Then, the C Band has a frequency range from 4 GHz to 8 GHz.
- Finally, the L Band has the lowest frequency range, from 1 GHz to 2 GHz.
Therefore, the correct arrangement in descending order of frequencies is: Ka Band, X Band, C Band, L Band. This corresponds to the option:
(a) (a) (d) (c) (b)
So, the correct answer is (a) (d) (c) (b).
