The correct answer is: B. Refraction.
Refraction is the bending of light as it passes from one medium to another. This is because light travels at different speeds in different media. When light passes from air to water, for example, it slows down and bends towards the normal. The normal is an imaginary line perpendicular to the surface at the point of incidence.
Eclipses occur when the Moon passes between the Earth and the Sun, or when the Earth passes between the Sun and the Moon. In a solar eclipse, the Moon casts a shadow on the Earth.
If you are in the path of the Moon’s shadow, you will see a total solar eclipse. If you are outside the path of the Moon’s shadow, you will see a partial solar eclipse.In a lunar eclipse, the Earth passes between the Sun and the Moon. The Earth casts a shadow on the Moon. If you are on the side of the Earth that is in the Earth’s shadow, you will see a total lunar eclipse. If you are on the side of the Earth that is not in the Earth’s shadow, you will see a partial lunar eclipse.
The following are the incorrect answers and their explanations:
- A. Reflection is the bouncing of light off a surface. This is how we see objects. When light hits an object, some of the light is absorbed by the object, and some of the light is reflected back. The reflected light is what allows us to see the object.
- C. Rectilinear propagation is the straight-line path that light travels. This is because light is a wave, and waves travel in straight lines.
- D. Diffraction is the bending of light as it passes through a narrow opening or around an obstacle. This is because light is a wave, and waves can bend around obstacles.
