An optical communication system, having an operating wavelength,`lambda`(in meters), can use only x% of its sourcefrequency as its channel band width.The system is to be used for transmitting TV signal requiring a band width of F hertz. How many channels can this system transmit simultaneously?

Explanation

To solve the problem, we need to determine how many channels an optical communication system can transmit simultaneously given the parameters of operating wavelength (λ), percentage of source frequency (x%), and the bandwidth required for transmitting TV signals (F Hz).

### Step-by-Step Solution:

1. **Calculate the Source Frequency (f_source)**:
The frequency of electromagnetic waves can be calculated using the formula:
\[
f_{\text{source}} = \frac{c}{\lambda}
