The speed of light in water is ............... `(2.25xx10^8//1.8xx10^8)` m/s

The speed of light in vacuum is 3 xx 10^8 ms^(-1)

The speed of light in media M_1 and M_2 are 1.5 xx 10^8 m//s and 2.0 xx 10^8 m//s respectively. A ray of light enters from medium M_1 to M_2 at an incidence angle i . If the ray suffers total internal reflection, the value of i is.

A fiber of length 10 cm is illuminated with light from an light emitting diode (LED) which is turned on and off repeatedely for equal amount of time. The speed of the pulse of light are 2.00xx10^(8)m//s and 2.1xx10^(8)m//s in fiber. Maximum frequency of LED os that pulse arrive without overlapping is 60X(KHz) . Calculate X .

Refractive index of water is 4/3. calculate the speed of light in water. Speed of light in vacuum is 3xx10^(8)ms^(-1) .

Refractive index of glass is (3)/(2) and refractive index of water is (4)/(3) . If the speed of light in glass is 2.00 xx 10^(8) m/s, the speed in water will be
