Diffraction increases
when size of the
slit
approaches
wavelength size.
|
 |
Which slit will
cause light to
diffract the most?
|
|
|
Answer
(A)
Diffraction is
greatest when
the slit is small compared
to the wavelength of
the wave.
|
Why does the amount of diffraction increase
as the
size of the slit decreases?
