In this magic trick, the oil and the quartz glass rod have the same index of refraction. So the light doesn’t change speed or direction when it passes from the oil to and quartz glass rod.

I am Willy Loman. I am the person who want others attention and is governed by a desire for success.I often mention my brother, who made a fortune in diamond mining in Africa because he represents everything I want for me and my son.
Though the debate we did on Friday. I think that it is fine to use nuclear but we can’t rely on it, it is dangerous and people might get hurt from it badly.
These are the benefits that we think during the debates.
1. Nuclear Power Generation Unlike fossil fuel power generation, which emits huge amounts of pollutants into the atmosphere, nuclear power generation will not create air
Pollution.
2. Nuclear power generation won’t produce carbon dioxide that aggravates the global warming effect.
3. Uranium fuel used in nuclear power generation has no other uses than power generation.
4. The energy density of nuclear fuel is millions of times higher than that of fossil fuels, so the fuel used by nuclear power plants is small in size, transport and storage
Are very convenient, a 1000 megawatt nuclear power plant only 30 tonnes of uranium fuel a year, a voyage of the aircraft can be completed
give away.
5. Among the costs of nuclear power generation, the proportion of fuel costs is relatively low, and the cost of nuclear power generation is less likely to be affected by the international economic situation
Therefore, the power generation cost is more stable than other power generation methods.
And these are the bad things that we talked about:
1. Nuclear power plants will produce high-level radioactive waste, or nuclear fuel used, although the share of small size, but because of having
Radiation, it must be handled carefully and subject to considerable political distress.
2. Nuclear power plant thermal efficiency is lower, so than the average fossil fuel power plant to emit more waste heat to the environment, so the heat of nuclear power plant
Pollution is more serious.
3. The investment cost of nuclear power plants is too large, and the financial risks of power companies are high.
4. Nuclear power plants are less suitable for spikes, peak-load operation.
5. Construction of nuclear power plants are more likely to trigger political disagreements.
6. There are a large number of radioactive substances in the reactors of nuclear power plants. If they are released to the external environment in an accident, they will be made to the ecology and people into injury.
