Convex Mirrors, Mirror Properties, and Concave Mirrors
About the Lecture
The lecture Convex Mirrors, Mirror Properties, and Concave Mirrors by Jared Rovny, PhD is from the course Geometrical Optics. It contains the following chapters:
- Mirror Properties
- Concave Mirrors
Included Quiz Questions
For a convex mirror, what is the reflection of a ray coming towards the mirror parallel to the mirror axis?
- The ray would reflect directly away from the focal point which resides inside the mirror.
- The ray would reflect directly towards the focal point on the same side of the mirror.
- The ray would reflect directly away from the focal point which resides outside the mirror.
- The ray would reflect directly parallel to the mirror axis.
- The ray would reflect directly towards the focal point which resides inside the mirror.
What is the difference between a “real” and “virtual” image?
- A “real” image can be physically cast onto a screen; a “virtual” image cannot
- A “virtual” image can be physically cast onto a screen; a “real” image cannot
- A “real” image and a “virtual” image are simply different names for the different sides of a mirror
- A “real” image can be physically seen; a “virtual” image cannot
- A “virtual” image can be physically seen; a “real” image cannot
If an object is placed 2 m from a convex mirror with a focal length of 1 m, where will the image appear?
- 0.66 m from the mirror and inside the mirror
- 0.5 m from the mirror and inside the mirror
- 1 m from the mirror and outside the mirror
- 3 m from the mirror and outside the mirror
- 0.66 m from the mirror and outside the mirror
