A-Level Physics Question Analyses Topic: Physics - Short Questions
Exam Questions:
1) How does the angle of minimum deviation of a glass prism vary, if the incident violet light is replaced by red light? Give reason.
2) Explain the process of release of energy in the installation at Chernobyl.
Answer:
For A-Level Physics, you should know:
1) The wavelength of the light has an inverse relationship with the refractive index. Since red light has a shorter wavelength than violet light, it has a lower refractive index.
Likewise, the angle of minimum deviation decreases when red light is substituted because it is inversely proportional to refractive index.
2) Energy is generated and released through the breaking of uranium atoms in a nuclear reactor.
A nuclear power plant's operation is based on the fundamental idea of getting thermal energy through nuclear fission of the atoms' nuclei from the fuel. A turbine will turn this heat energy, which is already steam, into mechanical energy. Finally, a generator will turn this mechanical energy into electrical energy.
Work hard for your A-Level Physics examination!
End of analysis. Great!
