Arrange the following communication frequency bands in the increasing order of frequencies
a. AM broadcast
b. Cellular mobile radio
c. FM broadcast
d. Television UHF
e Satellite communication

Options

A. a, b, c, d,e
B. a, c, b, d,e
C. e, b,d,c,a
D. a,c,d,b,e

Answer

To arrange the communication frequency bands in increasing order of frequencies, we need to first identify the frequency ranges for each band mentioned in the question:

1. **AM Broadcast**: 540 kHz to 1600 kHz
2. **FM Broadcast**: 88 MHz to 108 MHz
3. **Cellular Mobile Radio**: 896 MHz to 901 MHz
4. **Television UHF**: 420 MHz to 890 MHz
5. **Satellite Communication**: 6 GHz to 7 GHz (which is equivalent to 6000 MHz to 7000 MHz)

Now, let's convert all the frequency ranges to the same unit for easier comparison. We'll convert everything to megahertz (MHz):

- AM Broadcast: 540 kHz = 0.54 MHz to 1600 kHz = 1.6 MHz
- FM Broadcast: 88 MHz to 108 MHz
- Cellular Mobile Radio: 896 MHz to 901 MHz
- Television UHF: 420 MHz to 890 MHz
- Satellite Communication: 6000 MHz to 7000 MHz

Now we can list the lowest frequency of each band:

- AM Broadcast: 0.54 MHz
- FM Broadcast: 88 MHz
- Cellular Mobile Radio: 896 MHz
- Television UHF: 420 MHz
- Satellite Communication: 6000 MHz

Next, we will arrange these frequencies in increasing order:

1. **AM Broadcast**: 0.54 MHz
2. **FM Broadcast**: 88 MHz
3. **Television UHF**: 420 MHz
4. **Cellular Mobile Radio**: 896 MHz
5. **Satellite Communication**: 6000 MHz

Thus, the increasing order of the communication frequency bands is:

**a. AM Broadcast < c. FM Broadcast < d. Television UHF < b. Cellular Mobile Radio < e. Satellite Communication**
