The sum of the initial and final velocity divided by 2.
Answer:
The electromagnetic wave that travels the fastest through space is gamma ray
Explanation:
Electromagnetic wave is a type of wave which does not require material medium for its propagation. Examples of electromagnetic waves according to increasing frequency of the waves are gamma ray, x-ray, ultra violet ray, infra red, visible light, micro wave and radio waves.
Frequency of a wave is inversely proportional to period of oscillation of the wave. The higher the frequency of a wave, the shorter the period of oscillation. Gamma ray has the highest wave frequency in electromagnetic spectrum and shorter period of oscillation, thereby causing it to have the highest penetration power.
Rain that tends to fall in bands on earth is usually caused by : Warm, moist air rising and cooling
First, the water on earth evaporate due to sun's heat and formed cloud. Later on, this water condensed and fall again on the earth. Completing the water cycle
