Hello I really want to know what the advantages and disadvantages of optical pyrometers are? Thanks a lot

Oh right so the reason why these peaks appear is due to constructive interference from the diffracted laser beam. What is MDRs, I've been trying to search for it, on the internet but I can't find any relevant resources. And do IIRC and supernumerary rainbows occur in this experiment or is...

Yea I did control the refractive index, I set it to air. I manage to set everything according to the factors in my experiment. I'm just curious though the MiePlot graph is sort of an exponential decay one, with two smaller peaks as it exponentially decays. And the graph i produced using excel...

Can anyone tell me what the density of salt is on average? I know there are many types of salt, but there must be an average value to this right? Because I’ve got the volume of this salt particle and I need its density in order to work out the mass. I also want to plot a graph of Intensity...

Well the thing is, I have the voltage for each scattered angle, by moving a sensor. And I've plotted voltage vs scattered angle using Excel. And then using MiePlot I've tried entering values for size of particle, until I got the MiePlot graph to be more or less the same as the graph of voltage...

Hello, I'm quite intrigued as to why when a mist of water particles (clouds etc) is being shined by laser light, the laser beam is seen clearly, all throughout the mist, but if you take the mist off, the laser beam is no longer seen. What's the theory behind this? Thanks a lot From Steven

So there is no definite equation for the Mie Theory, that can give me the scattered angle, knowing the intensity and radius of particle under investigation? If this is the case I would have to use MiePlot which would essentially give me the size of the particle under investigation? Thanks.

Hello, can anyone tell me the equation to the Mie scattering. I have salt particles of a specific size, and I want to work out the Mie scattering of it. Thanks a lot From steve.

Hello, I'm having trouble finding the rest energy of delta, on the internet. Can anyone give me this value please. It's delta zero. i.e. its charge is 0 and strangeness is 0 too. Thanks a lot for your time From Steven
