The light moves from the source in a straight line to an object and then moves into the back of your eye to your retina.
starts from sun
We're modestly familiar with the source of heat and light. And we know that heat and light both exist and are real. Cold and darkness do not exist. They merely describe the lack of heat and light, respectively.
About 1100 feet per second, which is the speed of sound.
Light will not travel into silver.
Torch light is NOT a natural source of light. It is an Artificial Source of light generated by the electrical energy. In this the electrical energy is being transformed into Light energy.
Light can travel through undistorted
the photons travel outward from a light source in all directions.
the light goes into your pupiuls
Outward from the source.
I am not sure that there are many scientists who describe time travel. those that describe light waves are physicists.
They travel in open spaces
It depends how bright the source is.
yes,it is a source we can find the smell organisms
coherent
Light emitted by any light source - say, by a lamp, or by the Sun - travels in all directions.

Light requires nothing more than a source for transmission. sound requires a source and a medium to conduct it. In vacuum, there is no conductor for sound.
electromagnetic waves generally don't require a medium to travel. the most commonly visible example is "light" which may be either sun's light, light from a bulb or any other source. they travel as transverse waves.
