Show Roaring Sun I I ) The sun is a great roaring fur. nace. We see it but cannot hear it because noise is conveyed only by waves in matter, such as ail or liquids or solids. Light is con. veyed through a non-material "something" called the Ether, which seems to be everywhere. Between us and the sun is no material ma-terial substance, so sound cannot pass to us, only light. Incidentally, we may remark that if sound could come to us, as light does, from the sun, we should ell be permanently deafened. |
