Explanation:
The quantity Katie wants to find out is the number of seeds contained in each orange
Therefore, the required population = The number of seeds in a given orange

Therefore, in order to collect the data, she can gather a few oranges and see how many seeds are in each.
Great question. Albert Einstein proved that light acts as both a particle and a wave in his 1905 paper. This is called wave-particle duality.
With quantum mechanics, it is easy to prove that light behaves as both a particle and a wave.
When UV light hits a metal surface, it causes an emission of electrons. This "photoelectric effect" proves how light behaves.
