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...

Is there any effect of different colours of light (white, red, yellow, blue etc.) on the rate of photosynthesis? If yes, why?

Light is inevitable for the process of photosynthesis reaction. Naturally sunlight plays the vital role for this process. Light may be of different colours like white, red, yellow, blue etc....
