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.
I think 2,5,1 but im not sure
Choice C because the IMF and the World Bank focus their efforts on promoting world trade. Both agencies focus on the development, economic self-sufficiency, and the currency problems of developing countries. It does not directly focus on promoting world trade.
