Wave/Slit/Diffraction

 

 

 

Amount of Diffraction
 Depends on
 Wavelength &
Size of Slit

 

 

 

Press the up/down arrows to change slit size

Diffraction increases
when size of the
slit
 approaches  
wavelength size
.

 

 

 

 

Which slit will

cause light to

diffract the most?

 

 

 

A - Diffraction is

greatest when the slit is

small compared to the

wavelength of the wave.

 

 

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