I am a student of physics at school level. My last class lecture was on the topic refractive index.But can’t understood this topic. Can anyone help me?
Hi golap_ali. welcome to the forums
I can understand your confusion. AFAIK most indices begin wsith 0 not 1, so it is counterintuitive,

Let’s see if wikipedia can help you
In optics, the refractive index (or refraction index) of an optical medium is a dimensionless number that gives the indication of the light bending ability of that medium.
The refractive index determines how much the path of light is bent, or refracted, when entering a material. This is described by Snell's law of refraction, n1 sin θ1 = n2 sin θ2, where θ1 and θ2 are the angle of incidence and angle of refraction, respectively, of a ray crossing the interface between two media with refractive i...
