Fusion occurs when low mass nuclei, such as hydrogen collide and combine to form nuclei with greater masses.
Fusion could be the world's answer to clean unlimited amounts of energy.
Fusion is extremely difficult to contain and maintain here on earth.
Explanation:
Nuclear fusion is the combination of light atomic nuclei to form nuclei with greater mass.
The sun is powered by chain reaction involving fusion of light hydrogen nuclei to produce a more massive atom of helium.
- As with all nuclear reaction, mass is equivalent to energy. These reactions takes place place in the nucleus of an atom where nuclear forces are broken .
- it is known that nuclear fusion produces far more energy than fission reaction.
- It produces less radioactive wastes and could be the world's clean source of unlimited amount of energy.
- The major problem with fusion is that it is difficult to start and requires a a lot of energy to initiate.

<h2>
Answer: The spreading of waves behind an aperture ismore for long wavelengths and less for short wavelengths</h2>
Here we are talking about Diffraction and, in fact, waves diffract the most when their wavelength is about the same size of the gap or aperture.
Diffraction happens when a wave (mechanical or electromagnetic wave) meets an obstacle or a slit .When this occurs, <u>the wave bends around the corners of the obstacle or passes through the opening of the slit that acts as an obstacle, forming multiple patterns with the shape of the aperture of the slit.
</u>
<u />
Note that the principal condition for the occurrence of this phenomena is that the obstacle must be comparable in size (similar size) to the size of the wavelength.
In other words, when the gap (or slit) size is larger than the wavelength, the wave passes through the gap and does not spread out much on the other side, but when the gap size is equal to the wavelength, maximum diffraction occurs and the waves spread out greatly.
This means the smaller the slit or obstacle (diffracting object), the wider the resulting diffraction pattern, and the greater the obstacle, the narrower de resulting patter.
Answer:
Condensation
Explanation:
That is when water from the air collects as a drop. also can be rain.
Wind, running water, glaciers, waves, and gravity
According to a source, fringes is the answer. These fringes are what causes dark regions in the double -slit experiment conducted that can be observed in the screen.
