WebThe entire electromagnetic spectrum, from the lowest to the highest frequency (longest to shortest wavelength), includes all radio waves (e.g., commercial radio and television, microwaves, radar ), infrared radiation, … WebWind fetch. A long fetch creates a high energy wave. In oceanography wind fetch, also known as fetch length or simply fetch, is the length of water over which a given wind has blown without obstruction. [1] [2] Fetch is used in geography and meteorology and its effects are usually associated with sea state and when it reaches shore it is the ...
