Click For Summary
To calculate the spread in wavelength when a monochromatic light source is pulsed by a shutter, one must analyze the signal in the time domain. Performing a Fourier transform on this signal will reveal its frequency components, including all harmonics. The pulse duration directly influences the bandwidth of the resulting frequency spectrum. This relationship highlights the trade-off between time and frequency resolution in optical measurements. Understanding these principles is crucial for applications in spectroscopy and optical communications.

Hello,
here is a poser for you how do you calculate the spread in wavelngth when a monochromatic light source of known wavlength is chopped by a shutter into a known pulse duration?

Take the signal in the time domain and do a Fourier transform into the frequency domain. You'll obtain all the harmonics of that signal.

Thread 'Does acceleration affect impact energy vs constant velocity?'

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
