From: BURT on
Light can have any size of wave. If this is true won't some
wavelengths be too small to pass through the two slits?

Only certain sizes would go through. Light behaves immaterial if it
can pass through matter such as the partition between the two holes.
But light behaves immatterial all of the time. It gets into your
house
and radio as radio waves without any problem.
