by the way: this looks like a home work excercise....
Provided no other information, the power drops exponentially... staring with 1 dBm (miliWatt), continuously draw a linear dropping line in dB scale, with slope equal to the loss per unit length...
If I understand the information correctly, you can calculate as shown in the Excel file attached.
In physics, the description of the properties of light generally refers to its wavelength (nm), while in the range of microwaves and radio waves we refer to the frequency of a signal (e.g. kHz or...
