.Discuss the effect of varying the following parameters (all other parameters remaining unchanged) on the scattering properties () of nano/micro particles (for each part, you must state the parameter values or ranges used in MiePlot):

a. Refractive index of the sample

b. Refractive index of the surrounding medium

c. size of the nano/micro particles

[Use particle size range: 50 nm to 90 nm, particle refractive index range: 2.6 to 3.4 and surrounding medium refractive index range: 1 to 1.5]
