Question

which is high refractive index Water or glass?​

Answer 1

Glass has a higher refractive indexthan water. The refractive index of window glass is 1.52, while therefractive index of pure water is 1.33. This means that light travels throughglass slower than it travels throughwater.

Answer 2

the refractive index of glass(1.52) is higher than refractive index of water(1.33).(see table no.-10.3 in ncert)
