4. What the focal length means
What the focal length means
5. Two lenses, one stronger
Two lenses are cut from glass with the same refractive index, and the first has a radius of curvature of centimeters while the second has a radius of centimeters. Both are single surfaces. Which lens has the shorter focal length?
6. An object at infinity
A camera lens of focal length millimeters is aimed at a star, an object effectively at infinite distance. Where does the image of the star form?
7. Focal length from a conjugate pair
A lens forms a sharp image when the object sits centimeters in front of the glass and the sensor sits centimeters behind it. Using , compute the focal length in centimeters and write the number.
