33.3. The interaction between the electric field of an electromagnetic wave and the matter it passes through is responsible
for nearly all optical effects; hence this field is used to specify the direction of polarization.

33.4. (1) The larger the diameter, the greater the ability to resolve objects close together. (2) A larger diameter means that
more light reaches the eye from a given object; hence, it can be seen even if poorly illuminated.

33.5. The wavelengths of visible light are very short relative to the size of a building, so their diffraction is imperceptible.
The wavelengths of radio waves are more nearly comparable with the size of a building.
33.6. Even a weak light involves many photons per second. Visual responses persist for a short time, so successive photons
give the impression of a continuous transfer of energy.
