Q16.
When you place a candle 30cm from a lens, a real image of the candle forms on a paper 80cm
from the lens on the other side of the lens. What is the focal length of the lens to the tenth of a
centimeter?
21.8cm
Q17.
When you place a candle 30cm from a lens, a real image of the candle forms on a paper 30cm
from the lens on the other side of the lens. What is the focal length of the lens to the tenth of a
centimeter?
15.0cm
Q18.
You’ve trying to take a photograph of two small statue with a 200mm focal length lens, one 5
meters from the camera, the second 5 meters from the camera. Which of the following statement
is true?
The image of the two statues are both the same distance from the lens because photographs are
not 3D.
Q19.
Your camera has a lens with a focal length of 35mm. when you take a picture of the moon, how
far from the lens is the real image of the mountain?
