Type Answer HERE:
1. Without a picture provided, it is not possible to determine the type of line in the picture.
2. Refraction is the bending of light as it passes from one medium to another, while reflection is the bouncing back of light when it encounters a surface. The key factors that influence the behavior of light in refraction are the angle of incidence, the refractive indices of the two mediums, and the speed of light in each medium. In reflection, the angle of incidence is equal to the angle of reflection.
3. As the medium becomes denser, the angle of refraction tends to decrease. This is because the speed of light decreases as it passes from a less dense medium (e.g., air) to a denser medium (e.g., water). The angle of refraction is governed by Snell's law, which states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the refractive indices of the two mediums. As the refractive index of the denser medium increases, the angle of refraction decreases.
