Question
1.
Which rules apply to concave mirror ray tracing? Click all that apply.
If an incident ray travels through the focal point on the way to the curved mirror, the ray will be reflected back parallel to the principal axis.
If an incident ray travels parallel to the principal axis on the way to the curved mirror, the ray will be reflected back through the focal point.
If an incident ray travels toward the focal point on the way to the curved mirror, the ray will be reflected back parallel to the principal axis.
If an incident ray travels parallel to the principal axis on the way to the curved mirror, the ray will be reflected in away from the focal point behind the mirror.

Here are the answers to your questions:
1. **Which rules apply to concave mirror ray tracing?**
- **Correct Statements:**
- If an incident ray travels through the focal point on the way to the curved mirror, the ray will be reflected back parallel to the principal axis.
- If an incident ray travels parallel to the principal axis on the way to the curved mirror, the ray will be reflected back through the focal point.
- If an incident ray travels toward the focal point on the way to the curved mirror, the ray will be reflected back parallel to the principal axis.
2. **Parallel rays of light bouncing off a curved mirror converge on a single point called:**
- **focal point**
3. **A mirror with radius of curvature 0.5 meters has an object placed 0.1 meters in front of it. Where would the image be located?**
- **-0.17 meters** (Using the mirror formula \( \frac{1}{f} = \frac{1}{d_o} + \frac{1}{d_i} \) where \( f = \frac{r}{2} \)).
4. **A mirror of focal length -0.5 has an object in front of it at 1-meter distance. Where will the image be?**
- **0.33 meters behind the mirror** (Using the mirror formula).
5. **A ray of light is incident on a mirror at an angle of 30° from the surface. What angle would you expect the reflected light to make with respect to the normal?**
- **30°** (The angle of incidence equals the angle of reflection).
6. **If an object is placed a distance 0.3 meters away from a curved mirror, and the resulting image has a magnification of -5. What can you say about the mirror?**
- **it is concave** (The negative magnification indicates an inverted image, and such high magnification is usually associated with concave mirrors when the object is within the focal length).
7. **If an object is placed 0.5 meters from a curved mirror and the resulting image has a magnification of 0.7, what is the image distance?**
- **-0.35 m** (Using the magnification formula \( m = -\frac{d_i}{d_o} \)).
8. **As you walk away from a flat mirror, what is true of your image in the mirror?**
- **it stays the same size and distance away from the mirror.** (The distance of the image from the mirror is always equal to the distance of the object from it).
9. **An image formed by a mirror has a magnification of -0.7. What does that mean?**
- **the image is inverted and smaller** (The negative sign indicates inversion, and a magnification of less than 1 indicates the image is smaller).
10. **With respect to curved mirrors, the point where the principal axis meets the mirror is called the:**
- **vertex**
