What are the steps to determine image characteristics using a ray diagram?
- Draw the mirror and principal axis. 2. Draw the object. 3. Draw at least two principal rays accurately. 4. Locate the image at the intersection of the reflected rays. 5. Determine if the image is upright or inverted, real or virtual, and reduced, enlarged, or the same size.
What is the effect of placing an object at the focal point of a concave mirror?
The reflected rays are parallel, and no image is formed.
What is the effect of a magnification value greater than 1?
The image is enlarged compared to the object.
What is the effect of a negative magnification value?
The image is inverted.
What type of image is formed when an object is placed at the focal point of a concave mirror?
No image is formed; the reflected rays are parallel.
What effect does a magnification greater than 1 have on the image?
The image is enlarged.
What effect does a negative magnification have on the image?
The image is inverted.
