Wave and particles?!10 pts!!!!

It is always one or the other and never both at the same time)-A particle is a tiny object with a precise position at any moment (think of a bullet).The link below should be useful.......
i see "wave and particles" term used in many places but i dont understand the meaning of it.
pls can anyone explain?
thanks!

Consider the 2 Slit Experiment:

If we leave both slits open and do not observe which slit a given quantum went through we get a pattern of light and dark areas on a screen behind the slits. The location of the light and dark areas is perfectly described by the equations of wave mechanics ( this is absolute, irrefutable proof that light is a wave )

BUT......

If we place photoelectric cells on the screen we get discrete flashes of light in the light areas. (absolute irrefutable proof that light is a particle )

What to do?

One way out is to say that light has a dual nature and depending on how we observe it it behaves as either a wave or a particle. It is always one or the other and never both at the same time)

A particle is a tiny object with a precise position at any moment (think of a bullet).

A wave is an oscillating pattern which spread out (think of waves on a pond)
