Jo, det finns tv\u00e5 s\u00e4tt de kan f\u00f6rflytta sig. Markv\u00e5gor \u00e4r de som g\u00e5r direkt mellan s\u00e4ndarens antenn och radiomottagarens antenn.
\nDet finns runt jorden n\u00e5got som heter jonosf\u00e4r och som under vissa f\u00f6rh\u00e5llanden reflekterar radiov\u00e5gor. \u00c4ven jorden kan reflektera radiov\u00e5gor och detta kan p\u00e5g\u00e5 i flera steg. Dock minskar styrkan p\u00e5 radiosignalen ju l\u00e4ngre den f\u00e4rdats och ju fler g\u00e5nger den reflekterats, s\u00e5 till slut g\u00e5r den inte att h\u00f6ra.<\/span><\/p>\n

Det finns mycket mer att s\u00e4ga om v\u00e5gutbredning, du kan ju prova n\u00e5gon av l\u00e4nkarna h\u00e4r nedanf\u00f6r.<\/p>\n
