During an observation, it was noticed that light diffracts as it passes through small slits in a barrier. What does this evidence reveal about light?

It can travel in various wavelengths.
It can travel through the vacuum of space.
It demonstrates a behavior of energy.
It demonstrates a behavior of waves.

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )

c. magnitude and direction

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
