Is it possible to analysis variance of wavelength with pmt tube?

09 May 2017 1 9K Report

I'm going to desgin simple photospectrometer with pmt tube.

So, I want to check specific wavelength(450nm).

Is it possible?

A pmt does not have sufficient wavelength resolution to serve as the analysis device. The response of a pmt is wavelength dependent, but it is slowly varying.

You will need a wavelength dispersing device and slit.

Can we use the mean and SD to describe continuous data then during comparison the authors use Mann-Whitney U-test ?

As I understand if you use the mean and SD for describing your data, this means it is normally distributed and parametric. If so, the test for variance should be simple T test.
