Wave/Slit/Diffraction

 

 

 

Amount of Diffraction
 Depends on
 Wavelength &
Size of Slit

Diffraction increases
when size of the slit
  approaches  
wavelength size.

 

 

 

 

Which slit will

cause light to

diffract the most?

 

 

 

A - That slit width is

closest to the

wavelength of light

 

 

Why does amount of diffraction increase
as the size of the slit decreases?
