A laser beam is incident from the air at an angle of 30.00° to the vertical onto a solution of Karo syrup in water. If the beam is refracted to 19.24° to the vertical, what is the index of refraction of the syrup solution?

Respuesta :

Answer:

1.517

Explanation:

Angle of incidence in air, i = 30°

Angle of refraction, r = 19.24°

According to the Snell's law

[tex]n = \frac{Sini}{Sinr}[/tex]

Where, n be the refractive index of the syrup with respect to water. By substituting the values, we get

[tex]n = \frac{Sin30}{Sin19.24}[/tex]

[tex]n = \frac{0.5}{0.3295}[/tex]

n = 1.517

Thus, the refractive index of the syrup is 1.517.
