Dual nature of light

An acceptable theory in science is required to explain all the observations made on a particular phenomenon. Light, appears to have two different sets of behaviors under different circumstances. As you will see, sometimes light behaves like wave-form energy and sometimes it behaves like an extremely tiny particle. It required the very best scientific minds from all over the world to put together a theory to deal with the nature of light.

Dual nature of light

Unfortunately, Io did not turn out to be a good clock. The speed of light in a vacuum is a universal constant in all reference frames. The speed of light in a medium is always slower the speed of light in a vacuum.

The speed of light depends upon the medium through which it travels. The speed of anything with mass is always less than the speed of light in a vacuum. Brightness is the relative intensity as perceived by the average human eye.

The frequency of a light wave is related to its color. Color is such a complex topic that it has its own section in this book. Monochromatic light is described by only one frequency.

Laser light is effectively monochromatic. There are six simple, named colors in English and many other languages each associated with a band of monochromatic light. In order of increasing frequency they are red, orange, yellow, green, blue, and violet. Light is sometimes also known as visible light to contrast it from "ultraviolet light" and "infrared light" Other forms of electromagnetic radiation that are not visible to humans are sometimes also known informally as "light" Polychromatic light is described by many different frequencies.

Nearly every light source is polychromatic. White light is polychromatic. A graph of relative intensity vs. Although frequently associated with light, the term can be applied to any wave phenomena. A continuous spectrum is one in which every frequency is present within some range.

Blackbody radiators emit a continuous spectrum. A discrete spectrum is one in which only a well defined set of isolated frequencies are present. A discrete spectrum is a finite collection of monochromatic light waves. The excited electrons in a gas emit a discrete spectrum.

Dual nature of light

The wavelength of a light wave is inversely proportional to its frequency. Phase differences between light waves can produce visible interference effects.

There are several sections in this book on interference phenomena and light. Falcon can see a 10 cm. The flicker fusion rate is the frequency with which the "flicker" of an image cannot be distinguished as an individual event.

Like the frame of a movie… if you slowed it down, you would see individual frames. Speed it up and you see a constantly moving image.Jun 12,  · The dual nature of light is that it is both an object having mass and a waveform of moving force.

Photons at once have mass and occupy space yet do not remain still at any time as they are moved along by the energy of their metin2sell.com: Resolved. Dual nature of light - to explain various phenomena, light must be described sometimes as a wave and sometimes as a particle Light is not really a wave, nor is it really a particle.

Start studying The Dual Nature of Light. Learn vocabulary, terms, and more with flashcards, games, and other study tools. The dual nature of light suggests that light exhibits the characteristics of both waves and particles.

Light can seem to be particles in that it has discrete chunks (quanta, p hotons) of energy. The dual nature of light suggests that light exhibits the characteristics of both waves and particles.

Light can seem to be particles in that it has discrete chunks (quanta, photons) of energy. The light and dark bands seen on the screen are the result of light waves doing the same thing.

The dark band is the absence of light, or when light waves cancel each other out, while the lighter bands are where light waves amplify each other.
