5. A flower with a height of 10.0 cm is located 50.0 cm from a
converging lens. It forms
an inverted image that is 6.00 cm high. What is the focal length
of the lens?
6. A beam of laser light (580 nm) passes through a double-slit
arrangement. The light
hits a screen 2.75 m away, and you notice that the distance
between the central
bright band and the one next to it is 6.50 mm. How far apart are
the two slits?
7. You shine light from a 640 nm laser onto a single slit of
width 0.150 mm that is
placed in front of a screen. You measure the distance on the
screen between the
second minima on either side of the central bright spot, and you
find them to be 2.20
cm apart. How far away is the screen?
