Want this question answered?
he said that light consisted of different wavelengths and when it is passed through a prism the wave lengths get split up and form different colours
Yes, it is as it produces light from electricity. As said in http://www.schoolsobservatory.org.uk/astro/stars/lumin.shtml
colour is defined by the reflection of light off a surface. So glass can be said to have no colour as light does not reflect off of it
No, a comet's dust tail reflects light from the sun.
it is because a mirror has a smooth surface.
The speed of light is not infinite. Light takes time to travel from distant galaxies to our eyes here on Earth. If a galaxy is 1 billion light years away, it has taken 1 billion years for the light emitted by said galaxy to reach us here, so (obviously) we are seeing the light emitted 1 billion years ago. In a sense, we are seeing 1 billion years into the past at the light emitted by that galaxy.
COHERENT WAVESWhen the light waves are emitted from a single source and they have the zero phase difference between them then the waves are said to be coherent. The coherent waves are shown below:

it looses energy , it gives off light in the form of a single photon.
Supposedly God said "Let there be light"
" He said let there be light, and then there was light"
As you said its a light cart.
A plant that responds to light is said to be photosensitive, and it is said to have the property of photosensitivity.
Albert Einstein said that.
Radiation is emitted from something and travels from its point of origin to somewhere else. When radiation hits something else (and is therefore stopped) the thing that has been hit is said to have been irradiated. Thus a sunbather is undergoing irradiation by radiation emitted by the sun.
