Question: how fast is the speed of sound

Keywords: , ,

  1. on land approx 330 metres per second. IN the sea approx. 1500 metres per second.
    So if you heard a big bang 1km away with one ear in the sea and one in the air. there would be two bangs about two seconds apart.


  2. hahaaa, I never thought of it like that Simon. Good answer.


  3. I have no idea! I could “Google” it though if I needed to know! (or I could ask Simon!)


  4. I like that answer Simon. I can visualise someone testing that out.

    I remember being blown away as a child learning that light and sound had different speeds. It came up during a lightning storm when I realised that the sound of the thunder didn’t match up with the lightning. Such a great way to understand it!
