Acid rain is found in Sweden and is caused by air pollution in Britain and other countries of Europe. The pollution produced in Britain ends up mostly in Scandinavian countries- countries of northern Europe including Sweden, Norway and Denmark. In the USA, the winds blow air pollution to certain areas in Canada.
Acid rain has terrible effects on water life. Thousands of lakes in Scandinavia have no more life in them. They have received so much acid rain for so many years that life has been snuffed out and nothing can survive in these waters.
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.
