light is an electromagnetic wave composed of the seven major colours on the spectrum having diffetent wavelengths and frequencies.

light shows a dual nature some of the properties of the light can be explained on the basis of  the particle nature of light and some on the basis of the wave nature.

 

 

we can see objects when the light falling on them is reflected back to our eyes and falls on our retina.Eye is an optical instrument in the human body

It shows the things as it is

  The phenomenon such as Photoelectric effect and Copmtons effect cannot be explained even by the wave theory of light but were sucessfully explined on the basis of quantum theory

  The phenomenon such as Photoelectric effect and Comptons effect cannot be explained even by the wave theory of light but were sucessfully explined on the basis of quantum theory

we r able to see the things only when the light falling on the objects get reflected from the objects and falls on the retina of our eye.

our eye is an optical instrument which has the proper ty of showing the things as it is.

objects never emit colours they emit photons (photoelectric effect) when light rays fall on them. The frequency of the photon that matches with the frequency of the colour on the spectrum is said to be emitted by it.  E=h v
