Question

what happens to sound wavelength in the space?

Answer 1

By space you mean without atmosphere ?

Answer 2

the outer space yes

Answer 3

Sound travels in waves like light or heat does, but unlike them, sound travels by making molecules vibrate. So, in order for sound to travel, there has to be something with molecules for it to travel through. On Earth, sound travels to your ears by vibrating air molecules. In deep space, the large empty areas between stars and planets, there are no molecules to vibrate. There is no sound there.

Answer 4

thank you @Owen_Turner for the explanation but what i need exactly is to express wavelength as a change in equation or graph. not sure exactly which one of these works


here wavelength become wider until it become line



or this
