21Hey CEle!
I solved quite a chunk of da paper.... Its not that hard YAAR....
I thot i wud b real tuff.... Jus abt 10% of da stuff is non formula based.....
How much r u expecting buddy???
consider 5 identical rt angled isosceles prism of ref ind μ1,μ2,........μ5 resp
theyr arranged touching each other ( imagine 3 of em placed in str line and 2 of em placed btw the gaps by inverting them )
they r in order 1,2,3,4,5
given that in ray from air is at grazing incidence and final out ray also at grazing emergence
now prove
μ1^2 + μ3^2 + μ5^2 = 2 + μ2^2 + μ4^2

9this was obj for 1.5 marks !!!!!
i ve given u the correct option to prove
jus giv method as a wrong approach will make proof veeeery big
11as for the first one i tried
deviation produced by a single prism is (μ-1)A
adding all the individual deviations taking opposite sign for 2 and 4
it will be equal to 135°
i did not get the answer is there any mistake in my method please guide me
11angle of incidence =90 for grazing incidence
and for grazing emergence angle of refraction=90
