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 given communication frequency bands in increasing order of frequencies, we will first identify the frequency ranges for each option:

1. **AM Broadcast**: 540 kHz to 1600 kHz (or 0.54 MHz to 1.6 MHz)
2. **Cellular Mobile Radio**: 896 MHz to 901 MHz
3. **FM Broadcast**: 88 MHz to 108 MHz
4. **Television UHF**: 420 MHz to 890 MHz
5. **Satellite Communication**: 5.925 GHz to 6.425 GHz (or 5925 MHz to 6425 MHz)

Now, we will convert all frequency ranges to the same unit for easier comparison. We can use megahertz (MHz) for this purpose:

- AM Broadcast: 0.54 MHz to 1.6 MHz
- Cellular Mobile Radio: 896 MHz to 901 MHz
- FM Broadcast: 88 MHz to 108 MHz
- Television UHF: 420 MHz to 890 MHz
- Satellite Communication: 5925 MHz to 6425 MHz

Next, we will list the lowest frequency of each band:

- AM Broadcast: 0.54 MHz
- FM Broadcast: 88 MHz
- Television UHF: 420 MHz
- Cellular Mobile Radio: 896 MHz
- Satellite Communication: 5925 MHz

Now, we can 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** (5925 MHz)

Thus, the increasing order of frequencies is:

**A (AM Broadcast), C (FM Broadcast), D (Television UHF), B (Cellular Mobile Radio), E (Satellite Communication)**

### Final Answer:
A, C, D, B, E
