Answer:

Refractive index of the glass is 1.71

Step-by-step explanation:

As we know that when light enter from one medium to other medium then due to refractive index change light bends away or towards the normal

This phenomenon is known as refraction of light and as per Snell's law we have

$\mu_1 sin\theta_1 = \mu_2 sin\theta_2$

so we have

$1 sin31.2 = \mu sin17.6$

$\mu = (sin31.2)/(sin17.6)$

$\mu = 1.71$
