- Light transmits spatial and temporal information. This property forms the basis of the fields of optics and optical communications and a myriad of related technologies, both mature and emerging. Technological applications based on the manipulations of light include lasers, holography, and fibre-optic telecommunications systems.
1. Sunlight. The light that we receive from the sun is a prominent example of visible light in real life. The sunlight appears to be white in colour, but contains a set of seven colours arranged in a specific order according to the value of wavelengths.

Prism. A prism is a piece of laboratory equipment made up of glass or silicon that is generally used to display the existence of dispersion phenomenon in real life. When a ray of white light is made to strike the surface of a prism, it gets split into a spectrum of light.

Dec 7, 2022 · Light has the properties of waves. Like ocean waves, light waves have crests and troughs. The distance between one crest and the next, which is the same as the distance between one trough and the next, is called the wavelength .

- Compact Disk. Compact Disks are most susceptible to the process of diffraction. The surface of the compact disk is shiny and consists of a number of grooves.
- Hologram. Hologram, the word has been derived from two Greek words, ‘holo’ means whole, and ‘gram’ means a message. It is one fine technology that promises us an incredible future.
- Light entering a dark room. Suppose, there is a room with no light source, plus the light from the door is forbidden to enter the room as it is closed, and when someone opens the door partially, you can observe that the light gushes inside with a bend across the edges and around the corners of the door.
- Crepuscular Rays. You must have seen this breathtaking view for at least once in your life. These magnificent looking rays are known as crepuscular rays or God rays.
Oct 17, 2015 · The main quantifiable properties of EM radiation, or light, are the wavelength, intensity and photon energy. The wavelength is used to determine the type of wave involved. Whereas the intensity of light is related to the amount of photons present, which essentially “concentrates” energy.
Nov 14, 2024 · Light from the Sun warms the Earth, drives global weather patterns, and initiates the life-sustaining process of photosynthesis; about 10 22 joules of solar radiant energy reach Earth each day. Light’s interactions with matter have also helped shape the structure of the universe.
The cones respond to bright light; other structures called rods respond to dim light, and the pupil regulates the amount of light that enters the eye. The eye responds with maximum sensitivity to light at the middle of the visible color spectrum—specifically, green light with a wavelength of about 555 nm.
