well,it shines.
it travels about 8 mins, ie., 3*10^8 m/s(through vaccum) from sun to earth. it does not need a medium to travel. light exhibit both wave nature and particle nature.
A sonic wave.
Light is an electromagnetic wave.
No, they travel at the same speed
As an electromagnetic wave.
Yes, light waves can travel through air because air is a medium through which electromagnetic waves can propagate. Light travels at different speeds through different mediums, but it can definitely travel through air.
No. Light is an example of an electromagnetic wave, which can travel through a vacuum. Mechanical waves must travel through a medium, and cannot travel through a vacuum.
Light travels in the form of electromagnetic waves.
The simplest answer is that light consists of particles with wave properties. Elementary particles also have wave properties. This is how light travels.
A transverse wave of light can travel through air or gas.
Yes!!
No
The wave-particle duality theory. This explains why sometimes light appears to travel as a wave, and why sometimes it appears to travel as a particle.
