# Physics Unit 2 IAL May-Jun 2018 Thread watch

1. After the misery named Unit 1, let’s hope for a better examination this 18th May ❤️
2. i hope unit 2 goes well...any tips for revision
3. Check out Shawon Notes. They have good physics notes for Unit 2 as well
4. Suggest any notes,files,videos,etc for unit 2

6. Guys I need help on this one.

7. What is the answer to this ?

Guys I need help on this one.

phase difference=(2pi/(lambda)) * distance between two points
therefore answer is (2pi/(340/160))*1 which is C

but to find wavelength we use speed/frequency. so why in this question opposite is happening.

hope you can understand now
13. yes thankss

find the wave length of the wave using wavelegth= speed/frequency, then divide 1 metre by the wavelength. multiply what you got with 2 pi.

Why can't they teach us useful formulas like this in class? Damn
