Answer:
1.5
Explanation:
Light Refraction and Snell's Law
When light gets refracted and deviates upon entering a different medium, it will go closer to the normal because of the decceleration in speed. Upon entering a new medium, it moves 10.53* closer to the normal, therefore the angle of refraction is 30-10.53 = 19.47*.
To calculate the refractive index of the glass, you have to use snell's law
[tex]n_1sin\theta_1=n_2sin\theta_2[/tex]
where:
n1 = initial refractive index = 1.00 (air)
n2 = second/new refractive index = x
angle1 = angle of incidence = 30*
angle2 = angle of refraction = 19.47*
Therefore, n2 can be found by dividing each side by sin(O)2
[tex]\frac{n_1sin\theta_1}{sin\theta_2} = n_2[/tex]
[tex]\frac{1.00sin(30)}{sin(19.47)} = n_2[/tex]
[tex]\frac{0.5}{0.33331324756} = n_2[/tex]
[tex]1.5 = n_2[/tex]
