Electromagntic wave, such as an X-ray.
Explanation:
- Electromagnetic wave does not require any medium to travel. These waves propagate outwards from the source.
- They can travel even through the vacuum of outer space.
- The major source is the sun which emits radiation in the form of the Electromagnetic spectrum.
- These waves travel through oscillating electrical and magnetic fields generated by the oscillating charged particles.
- These waves oscillate in the perpendicular direction of planes concerning each other and are in form.
- Electromagnetic waves travel at speed of light.
Answer:
D
Explanation:
Wind can be described by its direction and speed. Wind direction is described using the direction from which it is blowing. Westerly winds move from west to east, while easterly winds move from east to west. Wind speed can be described using measurements like miles per hour or levels on a scale called the Beaufort scale. The Beaufort scale divides wind speeds into categories and uses specific words for different strengths of wind. A “breeze” is a light wind, while a “gale” is stronger. On the Beaufort Scale, the strongest breeze is 31 miles per hour; any wind over 32 miles per hour is considered a gale.
