- Light travels as waves. These are transverse waves, like ripples in water.
18 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 ...
The change in direction of a beam of light as it travels from one material to another is called refraction. The diagram shows refraction of light passing into, and then out of, a glass block.
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.

These different colours of light have different wavelengths and frequencies. Red light has the longest wavelength, and the lowest frequency of the visible spectrum. Violet has the shortest wavelength, and the highest frequency of the visible spectrum.
Mixing coloured materials, such as paint, is an example of subtractive colour mixing. Red paint appears red to us because when white light strikes it, the red pigments reflect the red wavelengths of light and absorball of the wavelengths. This reflected light is what is seen by our eyes. The same is true for all of the other colours. So what about ...
Light travels very fast - at the speed of light in fact!Light travels as waves.Light travels in straight lines.Light has many particle-like behavior traits an in combination with movement (quantum physics and quantum mechanics), it has the ability to travel across large distances, disperse, emit rays, and absorb additional substances.
Einstein had a great explanation for this peculiar observation. He hypothesised light is made of particles, and is in fact not a wave. He then linked the intensity of light to the number of...

The part of optics dealing with the ray aspect of light is called geometric optics. Light can travel in three ways from a source to another location: (1) directly from the source through empty space; (2) through various media; (3) after being reflected from a mirror.
