Physics: Why do we describe light by referring to its wavelength, but microwaves and radar pulses by referring to their frequency?

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...

Udit Singh

Sir, I am making a low cost, real time Turbidity measuring instrument for our lab. In turbidity meter we use different kind of Sources like LED, Lasers etc. & It also use detectors, I placed my detector at degrees to my source IR LED. I put my water sample in between source and detector.

My detector is not showing proper output. So, I decided to replace my current light source (IR LED) and detector (Silicon diode). Can you suggest few photo-diodes, I can replace to my current design of the device???

Thanks
