You observe a light ray move from one piece of glass to another (a different type of glass) and the light ray bends towards the glass-glass interface (away from the normal) when it enters the 2nd piece of glass. You deduce that:

Answer:

second medium is less optical denser than first medium

Step-by-step explanation:

As per Snell's law we know that


\mu_1 sin\theta_1 = \mu_2 sin\theta_2

so here we know that


\theta_1 = angle of incidence


\theta_2 = angle of refraction

As we know that light ray goes away from the normal when it move from medium 1 to medium 2

so here angle of refraction will me more than the angle of incidence

so we have


(sin\theta_1)/(sin\theta_2) = (\mu_2)/(\mu_1)

since we know that


\theta_1 < \theta_2

so we have


(sin\theta_1)/(sin\theta_2) < 1


(\mu_2)/(\mu_1) <1

so we can say that


\mu_2 < \mu_1

so we can say that second medium is less optical denser than first medium
