Last question, do we take amplitude as 1 if it is not changing ?
no we cn take any value... as i told u that we can even take 1000... our only focus is on how the value of amplitude will chnge after passing the polariser... n how ths will affect the intensity...
n in the options we dnt have such large values for Intensity so i just assumed 1

so we assume it as 1,10,100,1000,10000 and so ? :

NAHI yaar..! I never Meant Duffer :/,,! Plus U r Way Smarter than Me... (Ma sha Allah)!
I Just Was Amazed..! Never Met many People Having Libra! I m the Only One in My Family..!
And Sooryy For Late Reply :)!
I know what you mean, Leave it....
I am not duffer, I know almost everything in Physics, except 4 to 5 concepts, that includes, 3 chapter of wave, projectile motion and radioactivity ._.
ye ek question nai aya it doesn't mean I am duffer.

Yes,:) how did u get that please explain me.

look u just have to use the formula
n*(lamda)=d*sin(theta)
where n is the order (its told the second order that means 2)
d is the spacing of lines (which we have to calculate)
lamda is the wavelength
put the values in the equation
2*(590*10^-9)=d*sin(43)
solve it u wil get 1.7 :)
