Question

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?

Answer 1

1.517

Step-by-step explanation:

Angle of incidence in air, i = 30°

Angle of refraction, r = 19.24°

According to the Snell's law

`n = (Sini)/(Sinr)`

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

`n = (Sin30)/(Sin19.24)`

`n = (0.5)/(0.3295)`

n = 1.517

Thus, the refractive index of the syrup is 1.517.
