Light waves traveling through air

In summary, light is a form of electromagnetic radiation that is visible to the human eye and travels at the speed of light in waves. It can be absorbed, reflected, or scattered by particles in the air and has different wavelengths that determine the color we see. The Earth's atmosphere plays a crucial role in allowing light to travel through air, and light waves can also travel through other mediums such as water and glass.

Even though light is a transverse wave it travels through air . Why?

Hi,

It propagates. Just like a wave in the water is transverse and still propagates.

Light is not a mechanical wave through air. Indeed you cannot have transverse mechanical waves in a gas because these (the mechanical waves) rely on shear stress in the medium. But light does not need the air to propagate, air is more "in the way" rather than an element necessary for propagation of EM waves.

What is light?

Light is a form of electromagnetic radiation that is visible to the human eye and is responsible for the sense of sight. It is made up of tiny particles called photons, which travel in waves at the speed of light.

How do light waves travel through air?

Light waves travel through air in a straight line, at a constant speed of approximately 299,792,458 meters per second. As they travel, they can be absorbed, reflected, or scattered by particles in the air, such as dust or water vapor.

What is the relationship between light waves and color?

Light waves have different wavelengths, which determine the color that we see. Our eyes are able to detect a small range of wavelengths, which we perceive as different colors. For example, red light has a longer wavelength than blue light, and we see it as a different color.

How does the atmosphere affect light waves?

The Earth's atmosphere plays a crucial role in allowing light waves to travel through air. It helps to filter out harmful rays, like ultraviolet radiation, and also acts as a medium for light to travel through. The composition and density of the atmosphere can also affect how light is scattered and absorbed.

Can light waves travel through other mediums besides air?

Yes, light waves can travel through other mediums besides air, such as water, glass, and even certain types of gases. However, the speed and behavior of light waves may vary depending on the medium they are traveling through.
