WOW WHAT?

Hey guys,

They said we heard all those mystic sounds because of physic. Creepy isn't it? the question is why we always heard all those laughing sounds, kids crying, dogs barking and many more only at night. When I was in foundation program, my physic lecturer, Madam Asyikin told us you heard them because of physic, he said “ if you want to be a ghost buster, you must learn physic” and we burst to laugh. How funny it is. hahahahaha.

                Guess what, its true because of the refraction of sound wave.  Sound wave will reflect faster on hot air compare to cold air. At night the temperature of air at the Earth’s surface is much hotter compare to the atmosphere. This cause sound wave that travel that travel to the Earth’s surface reflect downward. So, we can hear clearly at night even though the sounds is far away from us.  

                That’s all from me :)

p/s : correct me if I’m wrong
