transition of a charged particle between energy levels.
Robert Hooke (1635-1703) developed a "pulse theory" and compared the spreading of light to that of waves in water in his 1665 Micrographia ("Observation XI"). In 1672 Hooke suggested that light's vibrations could be perpendicular to the direction of propagation. Christiaan Huygens (1629-1695) worked out a mathematical wave theory of light in 1678, and published it in his Treatise on light in 1690. He proposed that light was emitted in all directions as a series of waves in a medium called the Luminiferous ether. As waves are not affected by gravity, it was assumed that they slowed down upon entering a denser medium.[28]
Thomas Young's sketch of the two-slit experiment showing thediffraction of light. Young's experiments supported the theory that light consists of waves.
The wave theory predicted that light waves could interfere with each other like sound waves (as noted around 1800 by Thomas Young). Young showed by means of adiffraction experiment that light behaved as waves. He also proposed that different colours were caused by different wavelengths of light, and explained colour vision in terms of three-coloured receptors in the eye.
Another supporter of the wave theory was Leonhard Euler. He argued in Nova theoria lucis et colorum (1746) that diffraction could more easily be explained by a wave theory.
In 1815 Ampere gave Fresnel an idea that the polarization of light can be explained by the wave theory if light were a transverse wave.
Later, Augustin-Jean Fresnel independently worked out his own wave theory of light, and presented it to the Académie des Sciences in 1817. Siméon Denis Poissonadded to Fresnel's mathematical work to produce a convincing argument in favour of the wave theory, helping to overturn Newton's corpuscular theory. By the year 1821, Fresnel was able to show via mathematical methods that polarisation could be explained only by the wave theory of light and only if light was entirely transverse, with no longitudinal vibration whatsoever.
The weakness of the wave theory was that light waves, like sound waves, would need a medium for transmission. The existence of the hypothetical substance luminiferous aether proposed by Huygens in 1678 was cast into strong doubt in the late nineteenth century by the Michelson-Morley experiment.
Newton's corpuscular theory implied that light would travel faster in a denser medium, while the wave theory of Huygens and others implied the opposite. At that time, the speed of light could not be measured accurately enough to decide which theory was correct. The first to make a sufficiently accurate measurement was Léon Foucault, in 1850.[29]His result supported the wave theory, and the classical particle theory was finally abandoned, only to partly re-emerge in the 20th century.

Anything that travels as a wave can interfere with another wave of the same kind. For example when a water drop falls into a bath the water ripples ( or shows waves ) that travel away from where the droplet fell. If two water drops were fell into the bath of water at the same time and were close together the waves would interfere with each other. This is called superposition. If the two waves meet at a peak their combined height will be twice as high, this would also happen if they met at two troughs of a wave, the resultant trough would be twice as deep as the troughs normally.
The same happens with light in an experiment called Young's double slit experiment. two slits are used to separate the light (as using two different light sources will not have waves that are in phase). This experiment produces fringes of light, dark line and lines of light. The light fringes are where the light is in phase, the dark fringes is where the two light waves are out of phase ( where one wave is at a peak and the other wave is at a trough, so when they superpose they have a resultant of zero as they are opposites or 'out of phase' )
Light exhibits refraction, reflection, diffraction, dispersion and, as noted so
briefly above, constructive and destructive interference among coherent
sources. All of these are characteristics of wave behavior.
Wave theory is a branch of physics that studies the properties of waves. In wave theory, the properties are examined separately from the origin of the wave.

that radiant energy both have electrical and magnetic properties.
the theory is very interesting but it is a2-f5+p-0=78p
Christiaan Huygens
Christiaan Huygens and Isaac Newton were both responsible for the knowledge we have today on the motion of light. Huygens proposed his wave theory for light's motion and Newton proposed the particle theory in the 17th century. It is accepted today that light moves in both wave form and particle form at once.
yes it supports the wave theory of light...
Particle theory of light can explain Photoelectric Effect,Compton effect,Pair production.... wave theory of light can explain interference,refraction...
Einstein. He stated that light acts as both a particle and a wave.
this is a much more complicated question than perhaps you realise. try looking up "wave particle duality" photons have the strange characteristic of haveing properties of both a wave and a particle.

Christian Huygens' was one of the first to suggest that light was a wave. His theory, the wave theory of light, stated this, it was opposed by Newton's idea that light was a particle. More recently, scientists such as Thomas Young and Max Planck proved this theory with experiments. So, simply put, the wave theory states that light is a wave, which, as far as we know, is correct.
yes it supports the wave theory of light...
It was Max Planck who used the particle theory of light.
Give a brief account of huygen wave theory of light
The wave theory, originally proposed by Robert Hooke in the 1600s, proposes that light can act as waves as opposed to particles. It claims that waves can interfere with each other as well as have additive effects. Also, different colors are different wavelengths.
