Answer 4

I think you just read the graph. For what values of the x-axis do we have a reading?

Answer 5

it doesnt say

Answer 6

Owait. When a photon is absorbed, we will not detect it. So what the machine does not detect have been absorbed.

Answer 7

?

Answer 8

OK see it this way: You have 20 labeled cows. The question says some of your cows were eaten. And so you do a count and looked for your cows and you get the graph. So which cows were eaten?

You see the green and blue cows. That's why the graph says there's something there.
