Hi,
I have tried tackling these question but I am simply absolutely lost...
1. A single slit of width 1.50 um is illuminated with light of wavelength 500.0 nm. Find the angular width of the central maximum.
I have no attempt for number 1.
2. Microwaves of wavelength 2.8 cm fall on a slit and the central maximum at a distance 2 m from the slit is found to have a half width of 0.67 m. Find the width of the slit.
Well, I tried to find the angle by dividing 0.67/1. To find the slit width I then dividing 0.028 by 0.67. But my answer was wrong according to the book.
Any help is appreciated.
Thanks,
Peter G.
