Question

The relative index of glass is 1.5 that of water is 1.3 if the speed of light is water is 2.25×10^8m/s.what is the speed of light is glass​

Answer 1

Answer:

what is dicrimination

Answer 2

$\bold{\underline {Given:}}$

REFRACTIVE INDEX OF GLASS=1.5

REFRACTIVE INDEX OF WATER=1.3

SPEED OF LIGHT IN WATER=2.25*10∧8

1.5/1.3=X/2.25*10∧8

X=SPEED OF LIGHT IN WATER

X=2.25*10∧8*1.3/1.5

X=2*10∧8 m/s (APPROX)
