Physics - Electricity, Magnetism, Waves, and Light

Please answer the following questions succinctly and completely.

1. Chapter 9 - Describe how electric fields and magnetic fields are similar and how they are different. An electric field is a field of force, surrounding a charged particle, while a magnetic field is a field of force surrounding a permanent magnet, or a moving charged particle. When a charge is moving, it does not only have an electric field, but a magnetic field as well. This is why electric and magnetic fields are always associated with each other. They are two different fields, but not a totally separate field. Electric and magnetic fields are perpendicular to each other.

2. Chapter 9 - Indicate if each of the following statements is correct or incorrect.

[A] Electric fields are caused by electric charges.
[B] Moving electric charges cause magnetic fields.
[C] Direct electric current is used in transformers.
[D] Most housing is wired using parallel circuits.

3. Chapter 10 - How are electric motors and electric generators similar and how are they different?

4. Chapter 11 - How does wave speed relate to wave frequency? If the speed of a longitudinal wave is 340 m/s and the frequency is 1000 Hz, what is the wavelength of the wave?

5. Chapter 11 - Can sound wave travel through outer space? Why or why not?

6. Chapter 11 - What is the fundamental difference between a radio wave and a visible light wave?

7. Chapter 11 - What type of waves are light waves?

8. Chapter 12 - Give an explanation for why the sky is blue.

9. Chapter 13 - What is refraction and how does it occur?
