Answer:
second medium is less optical denser than first medium
Explanation:
As per Snell's law we know that
[tex]\mu_1 sin\theta_1 = \mu_2 sin\theta_2[/tex]
so here we know that
[tex]\theta_1 [/tex] = angle of incidence
[tex]\theta_2[/tex] = 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
[tex]\frac{sin\theta_1}{sin\theta_2} = \frac{\mu_2}{\mu_1}[/tex]
since we know that
[tex]\theta_1 < \theta_2[/tex]
so we have
[tex]\frac{sin\theta_1}{sin\theta_2} < 1[/tex]
[tex]\frac{\mu_2}{\mu_1} <1[/tex]
so we can say that
[tex]\mu_2 < \mu_1[/tex]
so we can say that second medium is less optical denser than first medium
