Young's Double-Slit Experiment

[applesnjanono]

Homework Statement

a) What are the factors that contribute to the error in the measurement of the wavelength of laser light?

b) Are there methods you might use to reduce the error, given that the wavelength of the laser light is known to at at least four significant digits?

The Attempt at a Solution

All i can come up with are human errors. and to improve it = placing laser on a flat surface, stable surface, projecting on a flat surface, and cleaning the slide.
What do you guys think? Thanks.

1] it is bcoz the electron would loses its energy i.e. y it although haviing a regular pattern maybe varying in the middle
2]well to how to lose it is through making it more excited
correct me if iam wrong
