Question

As we know that light and sound needs medium to travel. So how sun or some stars (which far away from sun), how their light reaches us?

Answer 1

Explanation:

No, let me correct you..

Light doesn't need a medium through which to travel because the speed of light is experimentally constant. But sounds need medium to travel.

Therefore, through this capability of light it can freely travel through space which is almost vaccum, due to this phenomenon light of stars like our sun can reaches us easily but sounds need a medium to travel and this is like a blessing of physics to us because this is preventing us from hearing loud sound of the thermo nuclear reaction which takes place in the core of all stars and the sound of largest explosion, the supernova

So this is what I think about your question

But I'm not sure if I'm right ?

Thanks
