2. The phenomenon of refraction is the bending of light as it passes from one medium to another, while the phenomenon of reflection is the bouncing back of light when it hits a surface.
In refraction, the key factors that influence the behavior of light are the angle of incidence, the angle of refraction, and the refractive indices of the two mediums. The angle of incidence is the angle between the incident ray and the normal (perpendicular) to the surface. The angle of refraction is the angle between the refracted ray and the normal. The refractive index is a measure of how much the speed of light changes when it passes through a particular medium compared to vacuum.
In reflection, the key factors that influence the behavior of light are the angle of incidence and the angle of reflection. The angle of incidence is again the angle between the incident ray and the normal, and the angle of reflection is the angle between the reflected ray and the normal.
3. As the medium becomes denser, the angle of refraction tends to decrease. This can be explained by Snell's Law, which states that the angle of refraction is dependent on the ratio of the refractive indices of the two mediums. When light passes from a less dense medium to a denser medium, the refractive index increases, and therefore, the angle of refraction decreases.
