- Light is a type of electromagnetic radiation that can be detected by the eye. It travels as a transverse wave. Unlike a sound waves, light waves do not need a medium to pass through, they can travel through a vacuum.

Light, visible light, or visible radiation is electromagnetic radiation that can be perceived by the human eye. [1] Visible light spans the visible spectrum and is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz.
Jan 16, 2021 · The visible light spectrum is the region of the electromagnetic spectrum that human eyes see. It runs from wavelength of about 400 nanometers (nm) at the violet end of the spectrum to around 700 nm at the red end of the spectrum.
What are light waves? Light is a type of electromagnetic radiation that can be detected by the eye. It travels as a transverse wave. Unlike a sound waves, light waves do not need a medium...
Textbook Solutions. CBSE Notes. What is Ray of Light? Light is a form of Electromagnetic Radiation of any Wavelength whether it is visible or not. Light is made up of small packets of energy called Photons, consisting of Waves of Electromagnetic Radiations. Photons do not possess any charge or resting mass and travel at the speed of Light.
- The law of refraction is employed by Snell. This law of refraction is also known as Snell's law. The law of refraction states that the ratio of the...
- Beams of light can be of 3 types. They are parallel, convergent and divergent. Here, we have mentioned the definition of these three types of light...
- A Ray of Light can be described as the path of Light through which energy travels in a medium, and is represented by a straight line along with an...
- Three different types of Light Beams are there, namely parallel, convergent and divergent Light Beams.Parallel Light Beams are formed when the Rays...
- Rays and Beams of Light are an important part of Physics and it is important to have a very clear understanding of the topic. To understand all the...
- The Radiation formed from Electromagnetic Waves and which moves in a straight line. Lights can be classified into two categories, Natural Light and...
- Light Waves Travel in Several Directions at Once. So in our wave view of light, we say that the light wave is traveling in many directions at once, but now we are going to change our perspective to that of an observer and a source.
- Source and Observer Define a Ray. Alert. When most people encounter the idea of a light ray for the first time, what they think of is a thinly-confined laser beam.
- Spherical Wave Passes Through Imaginary Plane. Now suppose the plane is not imaginary, but instead reflects the wave. Every point on this plane becomes a source of a wavelet, but this time, the wave created by these wavelets is going in the opposite direction.
- Spherical Wave Reflects Off Plane. Thanks to the symmetry of the situation, it's not difficult to see that the reflected wave is identical to a spherical wave that has originated from a point on the opposite side of the reflecting plane, exactly the same distance from the plane as the source, and along the line that runs through the source perpendicular to the surface
When a light ray encounters a surface, one or more of the following three things occur, the light ray: Reflects off the surface and travels off in a different direction. Passes from one medium into the other and continue on a new, straight line path.
