Edexcel PHYSICS Doubts
MasterMath:
Isnt the distance between 2 adjacent maxima's a wavelength :S?
Look at 2009 June 20b.. >_>
The distance moved by the microphone between two adjacent maxima is
0.050 m.
Calculate the wavelength of the sound wave.
They say the answer is 0.1 ???
elemis:
The distance between 2 adjacent maximas = half a wavelength.

Few doubts:
Q11 (c)
Q16 (b) (never understood polarisation) >:(
Thankyou very much

Q.11]c)
you measure the distance between the compressions let's say it's 4 cm , you move the compressions backwards by 1 cm , I hope you got it ...if not let me know so that I scan my paper :)
16 (b)
My answer is ;
I would place a Polaroid film and observe .If the intensity decreased it means it might be polarized but I would confirm it by using another Polaroid fiml as an Analyser and rotate it by 90 and observe the intensity of the light ..it would be darker but not 100 % dark .
I hope you got my idea and excuse my poor representation :P
:D
Malak:
I get he second one,
But for Q11, why would you move it backwards by 1 cm ???
Thx
