Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.What's the answer??
Answer is 2
wtf does the prism do
thin prism so
refractive index = A + d / A, where d is the angle of minimum deviation
A is the angle of prism = 4 deg
solving, we get d = 2 degrees
the prism just tilts the ray of light by 2 degrees
This is what I am getting
I keep getting 4
I think they've made a mistake in the very last step by missing an addition
v is 30 yes, but that means x coordinate is 30+30 =60
Since origin isn't at lens but at object
If you take origin at lens, you get 2
Yep, I am also getting 4
Tried various methods but still getting 4 as the answer
I guess something has to be done with the refractive index of lens, otherwise they wouldn't give it
Oh wait why is that given?
Huh
They've already given focal length though so it shouldn't really matter
we good?
