Here are the answers to the questions based on the principles of color and light:

1. **Magenta light is shone through a yellow filter, what color will the resulting light be?**
- **Answer:** Red
- Explanation: Magenta is made up of red and blue light. A yellow filter absorbs blue light. Therefore, only the red component will pass through, resulting in red light.

2. **White light is shone through a cyan filter, what color will the resulting light be?**
- **Answer:** Cyan
- Explanation: A cyan filter allows blue and green wavelengths to pass through, which together appear cyan.

3. **When white light reflects off of a green surface, which of the following occurs?**
- **Answer:** Only the green wavelengths of light are reflected.
- Explanation: A green surface reflects green wavelengths and absorbs all other wavelengths in the visible spectrum.

4. **What color of light results from the addition of cyan light and red light?**
- **Answer:** Magenta
- Explanation: Cyan light consists of blue and green. When you add red to it, the resulting combination is magenta.

5. **Which wavelength region of the electromagnetic spectrum might be used by a medical doctor to take images of your bones?**
- **Answer:** X-ray
- Explanation: X-rays have the penetration power necessary to image bones.

6. **White light shines on a sweater and green light is found to be missing after reflection. What color is the sweater?**
- **Answer:** Magenta
- Explanation: A sweater that appears magenta reflects red and blue light and absorbs green, appearing with missing green light.

7. **White light shines on a black surface. What colors of light are absorbed?**
- **Answer:** All
- Explanation: A black surface absorbs all wavelengths of visible light.

8. **Which of the following is not an example of an electromagnetic wave?**
- **Answer:** Sonar
- Explanation: Sonar uses sound waves for detection, while microwaves, visible light, and ultraviolet are all electromagnetic waves.

9. **When a yellow light shines on a wall painted with a cyan pigment, what color will the wall appear?**
- **Answer:** Green
- Explanation: Yellow light contains red and green wavelengths, and the cyan pigment reflects blue and green while absorbing red; so it will reflect the green component of the yellow light.

10. **What happens when you shine blue light on yellow paper?**
- **Answer:** It appears black
- Explanation: Yellow paper reflects red and green light. When blue light is shone on it, there’s no light to reflect back, causing it to appear black.

These answers are based on the principles of additive and subtractive color mixing as well as the behavior of light and surfaces.
