Solve problem C1 on page 20 of Physics 7 textbook.
Problem Statement:
Set up the experiment as shown in figure 7.1. Observe the image formed by the convex mirror and provide initial comments on the following properties:
1. Is the image virtual? Why?
2. Does the image appear larger or smaller than the object?
Solution:
1. The image is virtual because it cannot be captured on the screen.
2. The image is smaller than the object.
Solve problem C2 on page 21 of Physics 7 textbook.
Problem Statement:
Compare the width of the visible area of two mirrors.
Conclusion
Looking into a convex mirror, we observe a region... larger than when looking into a flat mirror of the same size.
Solution:
- The visible area of the convex mirror is wider than that of the flat mirror.
- Conclusion: Looking into a convex mirror, we observe a broader region compared to looking into a flat mirror of the same size.
Solve problem C3 on page 21 of Physics 7 textbook.
Problem Statement:
In cars and motorcycles, a convex mirror is often installed in front of the driver to observe the rear without a flat mirror. What are the benefits of doing so?
Solution:
In cars and motorcycles, people usually install a convex mirror in front of the driver to observe the rear without using a flat mirror because the convex mirror has a wider visible area, aiding the driver in observing the rear area more effectively.
Solve problem C4 on page 21 of Physics 7 textbook.
Problem Statement:
In areas with sharp turns and obstructing objects, a large convex mirror is often placed (figure 7.4). What purpose does that mirror serve for the driver?
Solution:
In areas with sharp turns and obstructing objects on the road, a large convex mirror is commonly installed because the wide visible area of the convex mirror helps drivers see the reflections of vehicles and individuals obstructed by objects on the side of the road, preventing accidents.
