A thin converging lens forms an upright virtual image 12 cm tall when the object is 8 cm tall. What is the magnification and what does its sign indicate?
A camera lens produces a small aperture (large f-number). How does this affect depth of field and image brightness?
Which ray through a thin lens passes undeviated (in a straight line) through the centre of the lens?
A thin lens produces a real image at 40 cm from the lens on the image side for an object placed 20 cm on the object side. What is the focal length?
An object 2.0 cm tall is placed 15 cm in front of a converging lens that produces an image 30 cm on the other side. What is the image height?
Which phenomenon explains why a prism separates white light into colours?
A diverging (concave) lens always produces an image that is:
A student uses the thin lens equation and obtains 1/f = 1/(-20 cm) + 1/(40 cm) and finds f = -40 cm. What type of lens and image does the negative focal length indicate?
Why do simple eyeglass lenses suffer from chromatic aberration (colours focusing at different distances)?
A thin converging lens has a focal length of 10 cm. An object is placed 30 cm from the lens. Using the thin lens equation, what is the image distance?
Which ray rule is correct when drawing ray diagrams for a thin converging lens?
