Final answer:

The calculation of the angle of refraction at F for a ray passing through a prism requires Snell's Law and knowledge of both the angle of incidence and the refractive indices of the materials involved. However, the necessary angle of incidence is not provided in the question.

Step-by-step explanation:

To calculate the angle of refraction at F for a ray passing through a prism with a refractive index of 1.49, we would need to use Snell's Law, which is stated as n1 sin(θ1) = n2 sin(θ2), where n1 and n2 are the refractive indices of the two mediums, and θ1 and θ2 are the angles of incidence and refraction, respectively. Unfortunately, the actual angles of incidence for the given problem are not provided in the question, so a direct calculation cannot be performed without this information. Typically, the refractive index of air (around 1.0003) is used as n1, and the angle of incidence would need to be known or provided to solve for the angle of refraction using the given refractive index of glass (1.49) as n2.
