Will a DC motor actually produce voltage if it is spun in reverse?
It'll make voltage if you spin it forwards, too. The only difference among a DC motor and a DC generator is what you use it for.
A long time ago, cars had DC generators on them instead of AC alternators. When you changed a generator, you had to "polarize" it so it would make electricity. You hooked it up to your battery and let it run, as a motor, for a few seconds. Don't try that with an alternator because you'll break it.
If you're looking for a neat little elementary-school science project, you can use little Radio Shack electric motors as generators for things such as windmills, water wheels, dynamos turned by bicycle tires..

Why diffraction can't occur if slit width is less than the wavelength of the light? Can you explain?
Resistance in Series: In such a combination the resistors give a single path to the passage of current and similar current passes by each of the resistors.
