- Light travels as waves. These are transverse waves, like ripples in water. The direction of vibration in the waves is at 90° to the direction that the light travels. Unlike sound waves, light waves can travel through a vacuum – they do not need a substance to travel through.
17 hours ago · According to Sapienza, this isn't the right question to be asking. "Light is not sometimes a particle and sometimes a wave," he said. "It is always both a wave and a particle. It's just that we ...
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,...
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.
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.
Nov 14, 2024 · When light travels through the air and into water, there is a change of speed as the light waves cross the boundary between the two different mediums. A medium is a material such as glass or water. The slowing down of the light causes it to change direction or ‘bend’.
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 rays change direction?
Waves have no preferred direction of propagation, so light that travels one path will, when reversed, follow the same path in the opposite direction. For this reason, it is not necessary to place an arrow-head on a ray in the above diagram.
