Question

Refractive index of water using convex lens and plane mirror experiment with readings

Answer 1

light has different properties one the properties include refraction ,reflection ,speed or velocity among others refractive e index is the refractive power of an object ,different medium have different refractive index .for example that of water is different from that of air or oil or any other medium .water for example have a refractive index of 1.33

refreactive index is therefore the ratio of the speed of light in a medium compared to the speed of light in another medium .a medium like glass has a refractive index of 1.57
