All light electromagnetic radiation travels at a constant speed. However, all light travels in waves. Different kinds of light are defined by the the wavelength of their light.
Many unique properties of light are extremely fascinating. Here, we will take one step closer to the wonders of light through its well-known basic properties. Is Light a wave or a particle?
Light has the properties of a wave and a particle. It is the distance that light travels in one oscillation, and is often expressed using a unit called "nanometer".
One nanometer is equal to one billionth of a meter. Our eyes can only see light that is of a wavelength between approximately to nanometers.
This range is called the visible light. The light of other wavelengths includes X-rays, ultraviolet rays, and infrared rays. Though we cannot see them directly, these are also members of the light family. On the other hand, light also has the property of a particle.
The intensity of Nature of light light varies depending on the number of particles. Bright light has many Nature of light while dark light has fewer particles. We can check out the particle property of light by comparing light with sound using a device called oscilloscope.
Sound is known to have the characteristics of a wave. When the intensity or magnitude of sound gradually weakens, the signal of sound becomes smaller and eventually disappears. However, when light gradually weakens, the overall quantity of its signal becomes less yet the few remaining pulses extremely short signals can be detected and the size of these individual signals does not decrease.
Surprisingly, light can travel around the earth 7. This property of light is utilized in many technical applications such as optical communications which transfer huge data in a very short time.
However, even light, which is faster than anything known to man, can move only 0. In recent years, research of such optical phenomenon that occur in these unbelievably short period of time, is becoming essential in new research fields of physics, chemistry, biology, and others.
Light travels around the earth 7 and a half times per second. Interaction of light with matter Light behaves in many different ways when it comes in contact with something. When in a vacuum such as outer space where no matter is present, light travels straightforward. However, light behaves in a variety of ways when it comes in contact with water, air, and other matters — it is "absorbed", "transmitted through", "reflected", and "scattered".
When light strikes matter, a part of that light is absorbed into the matter a and is transformed into heat energy. The sunlight striking a mountain bounces back in many directions. This is called reflected light. Our eyes see the mountain by capturing some of the light reflected from the mountain which directly reaches our eyes and then by forming an image of the reflected light on the retina through the lens of the eye.
Pink lines in the figure below represent the reflected light. To make it easier to describe, this figure shows a boy looking at a distant tree instead of a mountain. When there is a lake or pond between our eyes and a mountain, the light arriving there from the mountain reflects off the surface of the lake or pond blue dotted lines in the figure.
If the surface is calm with no wind and also flat and smooth such as on level surfaces with no irregularities like mirrors and glass, then the angle of the incident light angle of incidence and the angle of the light bouncing off the surface angle of reflection are equal to each other.Act natural with Natty.
Natural Light is the official beer of keeping it real and letting things just happen. Learn more about ice-cold Natty. Light has the properties of a wave and a particle. The word “wavelength” is used to express the wave or undulating property of light.
It is the distance that light travels in one oscillation, and is often expressed using a unit called "nanometer". •Light propagates itself “by its bootstraps!” –Light waves can interfere with other light waves, canceling or amplifying them!
–The color of light is determined by its wavelength.
•As a particle –Particles of light (photons) travel through space. –These photons have very specific energies. that is, light is quantized. Natures Light, Inc. is dedicated to offering the finest, affordable natural products.

Light with a lot of energy has a high frequency, i.e. the wavelength of light oscillates back and forth rapidly 'because' it has energy. Light with little energy oscillates slowly. This means that different kinds of light (or light of a specific wavelength) have specific amounts of energy that they carry in their waves.
Mead cites as the gross evidence of the exclusively wave nature of both light and matter the discovery between and of ten examples of pure wave phenomena, including the ubiquitous laser of CD players, the self-propagating electrical currents of superconductors, and the .
