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 are the key differences between real and virtual images?
Real images: Formed by convergence of light rays, can be projected. | Virtual images: Formed by apparent divergence of light rays, cannot be projected.
Compare and contrast concave and convex mirrors.
Concave mirrors: Converging, can form real or virtual images. | Convex mirrors: Diverging, always form virtual images.
