Thank you :)

Lovely! I must give you my sincere thanks for having helped me not only figure out the problem but assist me in understand why I need to do each step and how to do each step! Once again, thank you so much for having helped me understand this. Your Truly, Ben

Ok so if I understand correctly, I would need to use 2 seconds as my time period. V = F x λ V = 1/2 x 5 V = 2.5 m/s

Ok, I am glad I finally understood this. If you were given this problem could you possibly show me how you might have worked it out, as currently the steps it took me to understand seem very lengthy due to a lack of knowledge. For time period is that not 8 seconds?

Isn't it 20m? Because surely now it's just a case of: S = D/T S = 20/8 S = 2.5 m/s

20 m because if I now know that it will take 4 crests and the distance between them is 5 meters. 4 x 5 = 20.

Crest number four would be beside the boat 8 seconds later

Ok, so I have gotten this far... I drew this out as well on a piece of paper, but how can you know what the wave will be at 8 seconds if we cannot calculate at what speed the waves are traveling at?

This is where I have no ideas... My thoughts currently are that I have to do something with the 4 crests every 8 seconds but some how also use the information given in the question that the distance between each crests is 5 m. EDIT: Might, Speed = Wavelength/Period be helpful?

Ok I now confident with this, when you rephrased the question it helped! So I think this should now be correct: S = D/T S = 40/8 Speed of the Wave = 5 m/s Also: How come we would use this method of solving rather than using V = F x λ?

So for time I guess I would use 2? Also how could I figure how far the wave train travels during the 8 seconds if I don't have the speed yet. (D = S x T) Unless I would do 5 x 8 = 40.

Check the post just above, edited it.

Speed = Distance/Time So Then... Speed = 5/8 Speed = 0.625 m/s I still come out with the same answer.

1 Wave would take 2 seconds to pass... So would that mean that the wave travels at 2 m/s?

[FONT=Verdana]Hi, In class a few days ago, my teacher gave me a challenge question which they wanted me to answer. I have yet to succeed in finding the correct answer so I would be grateful for anybody who might be able to explain where I am going wrong with this problem! Homework Statement...
