Question

In the Roman soldier model for refraction, what angle do the soldiers now appearing to be walking at (remember they entered at 45 )?

A. 45
B. Less than 45
C. Greater than 45
D. Not enough info

Answer 1

In the Roman soldier model for refraction, the soldiers appear to be walking at an angle that is different from their actual direction of motion due to the bending of light at the interface between two media with different refractive indices.

Assuming that the soldiers entered the interface at an angle of 45 degrees, the angle at which they appear to be walking will depend on the refractive indices of the two media and the angle of incidence.

Since we are not given any information about the refractive indices of the media, we cannot determine the angle at which the soldiers appear to be walking. Therefore, the answer is D. Not enough info.

Answer 2

D. Not enough info

• The Roman soldier model for refraction is a helpful analogy to understand Snell's law, which describes the relationship between the angle of incidence and angle of refraction when light passes through different media. However, to determine the angle at which the soldiers (or light) appear to be walking after entering the second medium, we need additional information about the refractive indices of the two media involved.

Snell's law states:

n₁ * sin(θ₁) = n₂ * sin(θ₂),

where n₁ and n₂ are the refractive indices of the first and second medium, respectively, and θ₁ and θ₂ are the angles of incidence and refraction, respectively.

• Without knowing the refractive indices of the two media involved, we cannot determine the angle of refraction (θ₂) and cannot answer the question.
