Calculating the Refractive Index of the Glass Slab
To find the refractive index of the glass slab, we can use Snell's Law which states:
\[ \frac{\sin{i}}{\sin{r}} = \frac{n_2}{n_1} \]
where
- \( i \) is the angle of incidence
- \( r \) is the angle of refraction
- \( n_1 \) is the refractive index of the medium from which the light is coming
- \( n_2 \) is the refractive index of the medium into which the light is entering
Given Data:
- Angle of incidence, \( i = 30^\circ \)
- Angle of refraction, \( r = 20^\circ \)
- \( \sin{20^\circ} = \frac{1}{3} \)
- \( \sin{30^\circ} = \frac{1}{2} \)
Calculations:
\[ \frac{\sin{30^\circ}}{\sin{20^\circ}} = \frac{n_{\text{glass}}}{1} \]
\[ \frac{\frac{1}{2}}{\frac{1}{3}} = \frac{n_{\text{glass}}}{1} \]
\[ \frac{3}{2} = n_{\text{glass}} \]
Therefore, the refractive index of the glass slab is 1.5.
