In what form does light propagate in water?

Light is an electromagnetic wave, which propagates in the form of waves in water.

Fluctuation of light and particle properties;

Light shows both fluctuation characteristics and particle characteristics. This property is explained by wave-particle duality in quantum mechanics. When we talk about the propagation of light in water, we usually emphasize the fluctuation of light. The propagation mode of light wave is shear wave, that is, the vibration direction of electric field and magnetic field is perpendicular to the propagation direction of Apollo. This is the fluctuation of light waves.

How does light travel in water?

When light contacts water through air and other media, it will interact with water molecules. This interaction leads to the refraction of light. Refraction is a phenomenon that light changes direction when it passes through different media. According to Snell's law, when light enters the water, it will deviate to the normal direction, because the propagation speed of light in different media is different. The change of light direction is caused by the change of light speed.

The propagation speed of light in water:?

The propagation speed of light in different media depends on the optical density of the media. Light travels fastest in vacuum, but slower in water, glass and other media. This is because the interaction between light and matter and the electron cloud of matter leads to the decrease of the speed of light.

Refraction and reflection of light:

When light enters the water from the air, it will be refracted, that is, it will change the direction of propagation. This leads to the phenomenon that the position of the object seen in the water deviates, which is usually called refraction effect. At the same time, part of the light will be reflected back into the air, resulting in a reflection effect. That's why when you see objects on the water, they seem to appear underwater.

Color scattering of light:?

When light passes through water, light waves of different colors are scattered by water molecules in different ways. This leads to the fact that the refraction angle of light in water depends on its wavelength, which is why we see that the color of objects in water may change. Blue light waves scatter more strongly than red light waves, so we usually see blue tones in water.

Light propagates in waves in water, and its propagation mode in different media is influenced by the optical density of the media. The refraction, reflection and color scattering of light all play an important role in optics, which explains why what we see in water is different from what we see in air. These phenomena are also widely used in many fields, including underwater photography, glasses manufacturing, telescope and microscope design. The propagation of light in water is an important research field in optics and physics, and in-depth study can reveal the principles of many natural phenomena.
