I'm doing a planning exercise about wavelengths of nature sunlight. Could anybody explain for me, how to measure the wavelengths of sunlight please? thank you

measure the wavelengths in practical (lab condition). NOT by formula

Wavelength(W) * Frequency(F) = Speed of light (c)
If you know the frequency, then
W = c/F
c = 299,792,458 meters per second.

Sunlight has a number of wavelengths and either a prism or a grating is needed to separate the wavelengths into individual observable lines.

The answer is found in E = hf, where the frequency of a particular photon is multiplied times that of Plank's constant, a very small numerical value. There is no physical manner by which an individual wave is able to be determined as to its frequency. Most of the electromagnetic energy coming from the sun is very high frequency due to the point of origin. Probably your best choice would be to do a google search for "sunlight frequencies".

in visible light, the wave length is basically the color of the light.
To measure the wave lenghts of daylight, well... you can use an spectroscope but you should know that the light from the sun comes in many many different wave lengths so you'll just see a continuum.
