Thank you for being part of my lecture and completing the task!

My comments:

I'm not really convinced by your work. Some explanations have been too vague and they were not that clear either.
Regarding the second task, it's clearly shown that the wave 3 is much smaller than wave 1 and that's not correct.
Make sure you understand the topics given in the lecture before sumitting your work!

Overall score:
3/10
