at the start of the class we answered the exercises given by Mr. V and review for a bit about Diffraction.. (the larger the wavelength and the lower the frequency the greater diffraction we can have regardless of how large or how small the barrier is) ..He also gave us the notes for that lesson.
the next part he gave us the note for today's lesson Wave Interference in Two Dimensions..
he showed us two circular waves meeting each other to show the constructive and destructive interference happened between the two waves..
a constructive interference will occur in a crest to crest or trough to trough while the destructive interference can be produced when a crest and trough met. we also took up about nodal lines.. nodal lines are produced when a constructive and destructive interference are produced..
we can also calculate the wavelength of waves producing an interference pattern.. Its in the notes given, memorize and it will help..
that's all and if I'm not mistaken we will be having a lab tomorrow, and be ready for the test on Friday(if not postponed).
There is a volunteer to scribe next..
God bless to all and have a sweet dreams..

I'm Sorry it's Interference..
Thanks Meryll. You did a great job!
Mr.Vincent said the test is postponed to Monday.
