Write a scientific report about the theories and discoveries scientists made while studying the structure of the nucleus. Report Structure:
1- Introduction
2- Body:
a. Describe the components of the nucleus and how you can differentiate between them, also define how different isotopes are formed
b. Explain the uses of strong nuclear forces and its role in Einstein’s Energy equivalent to mass equation.
c. Differentiate between the three particle radiation types
d. Explain how a nuclear reaction occurs and give examples for nuclear reaction explaining nuclear fission
e. Search for how scientists used “The Standard Model” to detect new particles.
3- Conclusion

Antireflective coatings on solar cells are often made by applying a thin film of silicon nitride (sinx), which has an index of refractive of 1.2, on the top of the silicon solar cell, which has a refractive index of about 3.5. however, the sun emits radiation of various wavelengths which the solar cell absorbs, and the antireflective coating can only absolutely minimize the reflection of one of these wavelengths. the coating thickness is chosen to reduce the reflection of green/yellow light (e = 2.2 ev), which is the most intense color in the solar spectrum (shown below). which of the following coatings would minimize reflection of green/yellow light? the answer is 820 nm how? what is the angular width of the central maximum of an electron traveling at 2 x 108 m/s going through a single slit of width 1 mm.
