Homework Statement
Which electromagnetic wave would cause the most significant diffraction effect for grating diffraction?
a. infra red (10-5 m)
b. micro wave (10-2 m)
c. ultraviolet (10-8m)
d. X-ray (10-10m)
Homework Equations
The Attempt at a Solution
I know the most observable diffraction is when the wavelength is more or less the same as the gap width. So how can I know about the gap width? Gratings can have different gap width, depends on the number of lines per length.
I've tried several value of number of lines per length, such as 3500 lines / cm, 5000 lines / mm, etc and the closest answers are infra red and ultraviolet. My answer will be ultraviolet. Is there method or theory to determine the most significant diffraction?
Thanks
