What are the 7 types of light?
The EM spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency The common designations are: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays
What is the light answer?
Light is electromagnetic radiation that shows properties of both waves and particles Light exists in tiny energy packets called photons Each wave has a wavelength or frequency The human eye sees each wavelength as a different colour
What is light and types of light?
Light is electromagnetic radiation that can be detected by the human eye Electromagnetic radiation occurs over an extremely wide range of wavelengths, from gamma rays with wavelengths less than about 1 × 10−11 metres to radio waves measured in metres
What is called as light?
Light is just one form of electromagnetic radiation, or electromagnetic waves The smallest electromagnetic waves, with wavelengths the size of an atomic nucleus are called gamma rays In between are microwaves, infrared light, visible light, ultraviolet light and X-rays

What are all the types of light?
From lowest energy to highest energy (red to blue) there are radio waves, microwaves, infrared, visible light, ultraviolet, x-rays and gamma rays Each of them have their uses and, at the high energy end, they also have their dangers
What is light for kids?
Light is a form of energy The Sun is a very important source of light energy Without the energy from the Sun, there would be no plants or animals on Earth’s surface

What is light explain?
Light, or Visible Light, commonly refers to electromagnetic radiation that can be detected by the human eye Light can also be described in terms of a stream of photons, massless packets of energy, each travelling with wavelike properties at the speed of light
What is the 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 2 kind of light?
There are two basic types of light sources: Incandescence and Luminescence
What are the sources of light?
A light source is anything that makes light, whether natural and artificial Natural light sources include the Sun and stars Artificial light sources include lamp posts and televisions
Is light a wave?
Light Is a Wave – an Electromagnetic Wave!
Who invented light?
In 1802, Humphry Davy invented the first electric light He experimented with electricity and invented an electric battery When he connected wires to his battery and a piece of carbon, the carbon glowed, producing light
What Colour is the light?
There are three primary colours in light: red, green and blueColoured light Appearance of object in green light White paper Green (only green light to reflect) Red apple Black (no red light to reflect) Green apple Green
What is light small answer?
Light is a form of energy with which a human eye makes the things visible Light is defined as a form of electromagnetic radiation emitted by hot objects like lasers, bulbs, and the sun Light contains photons which are minute packets of energy
What is light energy?
Light energy is a form of energy and is expressed in joules It is the visible light that is detected by the human eye It is also the visible light that drives photosynthesis Blue and red wavelengths are the chlorophylls’ two most effectively absorbed wavelengths of the visible light

The Sun is the major source of light for the earth
What are the uses of light?
Uses of Light Energy Food formation Growth of the human body Regulation of Physiology Sight and vision Heat and temperature Drying & evaporation For speed regulation Source of electrical energy
What are the primary sources of light?
Answer: Light comes from different sources called light sources; our main natural light source is the sun Other sources include fire, stars and man-made light sources such as light-bulbs and torches
What are the 5 main characteristics of light?
Photography is “writing with light” So, let’s build our conversation about lighting on five fundamental characteristics of light: Direction, Intensity, Color, Contrast, and Hardness
What are the 5 main properties of light?
The primary properties of light are intensity, propagation direction, frequency or wavelength spectrum and polarizationCertain other mechanisms can produce light: Bioluminescence Cherenkov radiation Electroluminescence Scintillation Sonoluminescence Triboluminescence
What are the theories of light?
Newton’s corpuscular theory This theory could explain three main phenomena of light that is reflection, refraction, and rectilinear propagation of light This theory also says that the color of light is dependent on the size of the corpuscles
What is light with examples?
There are many example we see in our routine life carrying light energy like lightened candle, flash light, fire, Electric bulb, kerosene lamp, stars and other luminous bodies etc Each act as a source of light Even a burning candle is an example for light energy
What is the behavior of light?
Light behaves as a wave – it undergoes reflection, refraction, and diffraction just like any wave would Yet there is still more reason to believe in the wavelike nature of light
