Answer:
Yes, because when waves are at the same place at the same time, the amplitudes of the waves simply add together and this is really all we need to know!
Step-by-step explanation:
The sum of two waves can be less than either wave, alone, and can even be zero. This is called destructive interference.
If we place the waves side-by-side, point them in the same direction and play the same frequency, we will have constructive interference.
Answer:
1. S(1) = 1; S(n) = S(n-1) +n^2
2. see attached
3. neither
Step-by-step explanation:
1. The first step shows 1 square, so the first part of the recursive definition is ...
S(1) = 1
Each successive step has n^2 squares added to the number in the previous step. So, that part of the recursive definition is ...
S(n) = S(n-1) +n^2

2. See the attachment for a graph.

3. The recursive relation for an arithmetic function is of the form ...
S(n) = S(n-1) +k . . . . . for k = some constant
The recursive relation for a geometric function is of the form ...
S(n) = k·S(n-1) . . . . . . for k = some constant
The above recursive relation is not in either of these forms, so it is neither geometric nor arithmetic.
