What are the electromagnetic properties of light?
Light is electromagnetic radiation that has properties of waves. The electromagnetic spectrum can be divided into several bands based on the wavelength. As we have discussed before, visible light represents a narrow group of wavelengths between about 380 nm and 730 nm.
What is the physical nature of light?
Light is a transverse, electromagnetic wave that can be seen by the typical human. The wave nature of light was first illustrated through experiments on diffraction and interference. Like all electromagnetic waves, light can travel through a vacuum.
What are the three nature of light?
There are three measurable properties of wave motion: amplitude, wavelength, and frequency. A definitive experiment was Young’s double slit experiment, which demonstrated that light shined at two slits in a screen show an interference pattern characteristic of waves of light, rather than particles.
What are the 3 properties of light Class 6?
Following are the properties of light: Reflection of light: Every light follows the law of reflection which states that the angle of incidence is equal to the angle of reflection. Refraction of light: Refraction of light takes place when the light ray changes its velocity it passes from one medium to another.
What are the two nature of light?
In physics, there are two theories by which light can be defined: the first theory defines light as particles and the second theory as waves. When considering measurement equipment such as spectro[radio]meters, which measure light in wavelengths, the second theory is the most suitable to explain light.
Who is interested in the physical properties of light?
The physicist is interested in the physical properties of light, the artist in an aesthetic appreciation of the visual world. Through the sense of sight, light is a primary tool for perceiving the world and communicating within it.
How are refractive indices of two materials related?
Large differences between the refractive indices of two materials will result in a large amount of refraction when light passes from one material to the other. For example, light moves much more slowly through water than through air, so light entering water from air can change direction greatly.
How can we obtain other colours of light?
We can obtain other colours of light by mixing lights of primary and secondary colours. When white light shines on non luminous objects they reflect some colours and absorb all others.The colour of an object is the colour of light it reflects.A red object appears red because it reflects red colour of light and absorbs all the other colour.
Which is an example of the interaction of light and matter?
The study of light and the interaction of light and matter is termed optics. The observation and study of optical phenomena such as rainbows and the aurora borealis offer many clues as to the nature of light. An example of refraction of light.
