Light travels a distance x in time t1 in air and 10x in time t2 in another denser medium. What is the critical angle for this
- \(\sin ^{-1}\left(\frac{10 t_{1}}{t_{2}}\right)\)
- \(\sin ^{-1}\left(\frac{t_{2}}{t_{1}}\right)\)
- \(\sin ^{-1}\left(\frac{10 t_{2}}{t_{1}}\right)\)
- \(\sin ^{-1}\left(\frac{t_{1}}{10 t_{2}}\right)\)
Answer
(A) ^ -1 ( 10 t_ 1 t_ 2 )
