What are the steps for ray tracing with mirrors?
- Draw the setup (mirror and object). 2. Draw incident rays. 3. Reflect the rays. 4. Locate the image. 5. Analyze the image.
What are the steps for ray tracing with lenses?
- Draw the setup (lens and object). 2. Draw incident rays. 3. Refract the rays. 4. Locate the image. 5. Analyze the image.
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 positive image distance () in the mirror/lens equation?
The image is real and inverted.
What is the effect of a negative image distance () in the mirror/lens equation?
The image is virtual and upright.
What is the effect of a positive magnification (M)?
The image is upright.
What is the effect of a negative magnification (M)?
The image is inverted.
What is the effect of |M| < 1?
The image is reduced.
What is the effect of |M| > 1?
The image is enlarged.
What are the key differences between concave and convex mirrors?
Concave: Reflective surface curves inward, can form real or virtual images. Convex: Reflective surface curves outward, always forms virtual images.
What are the key differences between converging (convex) and diverging (concave) lenses?
Converging: Thicker in the middle, converges light rays, can form real or virtual images. Diverging: Thinner in the middle, diverges light rays, forms virtual images.
Differentiate between real and virtual images.
Real: Formed by actual convergence of light rays, can be projected on a screen. Virtual: Formed by apparent convergence of light rays, cannot be projected on a screen.
