Type Answer HERE:
1. Without the picture, it is not possible to determine the specific phenomenon occurring. However, if there is a line visible, it could indicate the presence of diffraction. Diffraction is when a wave bends or spreads out as it passes through an opening or obstacle. The line in the picture could be the result of light waves bending and interfering with each other.
2. Refraction is the bending of light as it passes through a medium with a different optical density. 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 at which the light ray hits the boundary, the difference in the optical densities of the two media, and the wavelength of the light. In reflection, the key factors are the angle of incidence (the angle at which the light strikes the surface) and the angle of reflection (the angle at which the light bounces off the surface).
3. As the medium becomes denser, the angle of refraction generally decreases. This is known as the principle of refraction. The denser medium causes the light to slow down and change direction, resulting in a smaller angle of refraction.
