If at angle `theta`the light takes maximum time to travel in optical fiber. Then the maximum time is `x xx10^(-8)`, calculate x.

The critical angle is maximum when light travels from

Sound takes some time to travel from one place to another. It will be maximum

Critical angle will be maximum, when light travels from

In vacum, to travel distance d, light takes time t and in medium to travel distance 5d, it takes time T. The critical angle of the medium is

In vacum, to travel distance d, light takes time t and in medium to travel distance 5d, it takes time T. The critical angle of the medium is

If X= A xx B and Delta X Delta A and Delta B are maximum absolute error in X ,A and B respectively , then the maximum relative in X is given by

If X= A xx B and Delta X Delta A and Delta B are maximum absolute error in X ,A and B respectively , then the maximum relative in X is given by
