1.8=300000÷speed of light in that medium
speed of light in medium=300000÷1.8=166666.667
speed of light in medium=300000÷1.8=166666.667

refractive index = speed of light in air ÷ speed
of light in medium.
so, 1.8 = 300000000 m/s ÷ speed of light in medium
[therefore], speed of light in medium = 300000000 m/s ÷1.8
speed of light in medium = 166,666,667 m/s
of light in medium.
so, 1.8 = 300000000 m/s ÷ speed of light in medium
[therefore], speed of light in medium = 300000000 m/s ÷1.8
speed of light in medium = 166,666,667 m/s
