i think i have the Solution
when light travels from denser to rarer medium then,
sin r / sin i = v1 / v2
so from given data,
→sin 90 / sin C = [x/t1]/[10x/t2]
→1/sin C = t2/10t1
→ sin C = 10t1/t2
→ C = arcsin(10t1/t2)
I think this is the right answer,
Please correct me if i am wrong.
the angle of incidence at which angle of refraction becomes 90 degress is critical angle.(C)
relation is
angle of refraction = 1/sinC
Another thing that i know is refractive index for vacuum is "1"
This is not homework..i am preparing for a competetive exam.
I could not figure out how to...
Light takes "t1" seconds to travel a distance "x" cm in vacuum and same light takes "t2" seconds to travel "10x" cm in a medium.The critical angle for the corresponding medium is .. ??
