44. The refractive index of kerosene is 1.1 times of therefractive index of water. The velocity of light inkerosene is 2 x 108 m/sec then the velocity of lightin water will be(1) 2 x 108 m/sec(2) 2.1 x 108 m/sec(3) 2.2 x 108 m/sec (4) 2.2 x 108 m/sec

Answer»

refractive.index of kerosene/refractive index of water=doped of light in kerosene/speed of light in waterhence as it is 1.1 times hencespeed of light in water will be 1.1*2*10^8=2.2*10^8m/s
