  We know that light is a wave based on how it behaves – it exhibits the same properties of other waves we have examined – it interferes with itself, it follows an inverse-square law for intensity (brightness), and so on.

As a result, different models describe different aspects of light’s behavior. The electromagnetic wave theory explains light’s ability to travel through a vacuum. The light ray model, on the other hand, can describe interactions between light and matter.

Apr 24, 2017 · Light always takes the shortest path between a source and destination. A line drawn from the source to the destination, perpendicular to the wave-fronts, is called a ray. Far from the source, spherical wave fronts degenerate into a series of parallel lines moving in the direction of the ray.

Jul 16, 2020 · Physics. Understanding light and other forms of energy on the move. This radiation includes visible light, radio signals — even medical X-rays. Light is a form of energy created by the movement of electrons. Different wavelengths appear as different colors, although most wavelengths are not visible to the human eye.

Like all electromagnetic waves, light can travel through a vacuum. The transverse nature of light can be demonstrated through polarization. In 1678, Christiaan Huygens (1629–1695) published Traité de la Lumiere, where he argued in favor of the wave nature of light.

What is the difference between electromagnetic wave theory and light ray theory?
As a result, different models describe different aspects of light’s behavior. The electromagnetic wave theory explains light’s ability to travel through a vacuum. The light ray model, on the other hand, can describe interactions between light and matter. Angle of incidence exceeds critial angle. Total internal reflection occurs.

Is light a wave?
This difficulty gets greatly magnified for the case of light. We know that light is a wave based on how it behaves – it exhibits the same properties of other waves we have examined – it interferes with itself, it follows an inverse-square law for intensity (brightness), and so on.

How do light waves travel?
Light is a type of electromagnetic radiation that can be detected by the eye. It travels as a transverse wave. Unlike a sound waves, light waves do not need a medium to pass through, they can travel through a vacuum. Light from the Sun reaches Earth through the vacuum of space. A short video explaining the concept of light waves.

Is light a form of energy?
Light is a form of energy created by the movement of electrons. Different wavelengths appear as different colors, although most wavelengths are not visible to the human eye. Light is a form of energy that travels as waves. Their length — or wavelength — determines many of light’s properties.

What is a range of wavelengths called?
The range of wavelengths, from super short to very, very long, is known as the light spectrum. Whatever its wavelength, light will radiate out infinitely unless or until it is stopped. As such, light is known as radiation. Light’s formal name is electromagnetic radiation. All light shares three properties. It can travel through a vacuum.

Is light a transverse wave?
Mathematics and experiments show that light is a transverse wave – the electric and magnetic field vectors point in directions that are perpendicular to the direction of motion of the light wave (and as it turns out, they also rare always perpendicular to each other).
