White light is defined as the complete mixture of all of the wavelengths of the visible spectrum. This means that if I have beams of light of all of the colors of the rainbow and focus all of the colors onto a single spot, the combination of all of the colors will result in a beam of white light.White light is nothing but colorless daylight. This contains all the wavelengths of the visible spectrum at equal intensity. In simple terms, electromagnetic radiation of all the frequencies in the visible range of the spectrum, appearing white to the eye is called white light.Light is one of the most important and versatile phenomena in nature. Like a courier, it can transfer information from one point to another. Like an alchemist, it can alter matter.

What makes a white light?
White light is a combination of all colors in the color spectrum. It has all the colors of the rainbow. Combining primary colors of light like red, blue, and green creates secondary colors: yellow, cyan, and magenta. All other colors can be broken down into different combinations of the three primary colors.
Is white light monochromatic in nature?
White light consists of different colors of light with different wavelength. Tthus it is a polychromatic light, not a monochromatic light.
What is a white light Class 7?
White light is composed of seven colours: violet, indigo, blue, green, yellow, orange and red. This can be observed with the help of Newton’s colour disc. It consists of the seven colours of white light.
Is white a color?
Some consider white to be a color, because white light comprises all hues on the visible light spectrum. And many do consider black to be a color, because you combine other pigments to create it on paper. But in a technical sense, black and white are not colors, they’re shades. They augment colors.
Who discovered the nature of white light?
In the 1660s, English physicist and mathematician Isaac Newton began a series of experiments with sunlight and prisms. He demonstrated that clear white light was composed of seven visible colors.

What is wavelength of white light?
Understanding the Colors That Make Up White Light
Essentially, that equates to the colors the human eye can see. It ranges in wavelength from approximately 400 nanometers (4 x 10 –7 m, which is violet) to 700 nm (7 x 10–7 m, which is red).
What is spectrum of white light?
The spectrum of white light consists of six basic colours arranged in a specific order: red, orange, yellow, green, blue and violet. Although Newton understood that a beam of light of a particular colour is always deviated by the same amount, he did not appear to understand why this is so.
What is frequency of white light?
Originally Answered: What are the frequencies of white light? All the frequencies in the range 405–790 THz . Visible spectrum – Wikipedia , since white light comprises of all the colors.
What color has the highest energy?
When it comes to visible light, the highest frequency color, which is violet, also has the most energy. The lowest frequency of visible light, which is red, has the least energy.
Why white light is the strongest light?
A true white light will have equal intensity in the low-end and the high-end of the spectrum, therefore more intensity on the high-end part than a yellowish light, and will be more energetic.

Is white light coherent?
While most white light sources have a poor spatial coherence, there are broadband sources with a high spatial coherence, sometimes even with the whole optical power delivered in a single spatial mode e.g. of an optical fiber.
Why is white light polychromatic in nature?
(i) Poly chromatic light consists of many colors each having its characteristic wavelength. White Light is polychromatic light because white light is made up of seven colours.
Which colour of light is monochromatic?
Monochromatic in science means consisting of a single wavelength of light or other radiation (lasers, for example, usually produce monochromatic light), or having or appearing to have only one color (in comparison to polychromatic).
What is the nature of light Class 7?
Light waves are electromagnetic waves so there is no need of medium for the propagation of these waves. They can travel in vacuum also. The speed of these waves in air or in vacuum is maximum i.e., 3 ´ 108 m/s.
What is light for 10th class?
Light is a form of energy that produces in us the sensation of sight. • Reflection of light is the phenomenon of bouncing back of light in the same medium on striking the surface of any object.
What is light in science for Class 8?
What is light? Light is a form of energy that enables us to see our surroundings when it gets reflected from objects around us. What is a reflection of light class 8? The change in the direction of light when it strikes the surface of an object is called reflection.
What color Is A Mirror?
So, what does a mirror reflect back? In white light, which includes the wavelengths of the visible spectrum, the colour of an object is dictated by those wavelengths of light that its surface atoms fail to mop up. As a perfect mirror reflects back all the colours comprising white light, it’s also white.
Is white a color physics?
If color is solely the way physics describes it, the visible spectrum of light waves, then black and white are outcasts and don’t count as true, physical colors. Colors like white and pink are not present in the spectrum because they are the result of our eyes’ mixing wavelengths of light.
Who first discovered color?
Our modern understanding of light and color begins with Isaac Newton (1642-1726) and a series of experiments that he publishes in 1672. He is the first to understand the rainbow — he refracts white light with a prism, resolving it into its component colors: red, orange, yellow, green, blue and violet.
Who explained the nature of light?
The earliest scientific theories of the nature of light were proposed around the end of the 17th cent. In 1690, Christian Huygens proposed a theory that explained light as a wave phenomenon. However, a rival theory was offered by Sir Isaac Newton in 1704.
