Student 1 is standing on a cart holding a small
stone, while student 2 is standing at rest on the
ground, as shown in the figure above. The cart is
moving at a constant speed v in the #r-direction,
as indicated by the coordinate system shown.
Student 1 drops the stone precisely when passing
student 2. Which of the following best represents
the path of the falling stone relative to student 1
and the path of the falling stone relative to
student 2 ?

Amichelson interferometer operating at a 600 nm wavelength has a 3.02-cm-long glass cell in one arm. to begin, the air is pumped out of the cell and mirror m2 is adjusted to produce a bright spot at the center of the interference pattern. then a valve is opened and air is slowly admitted into the cell. the index of refraction of air at 1.00 atm pressure is 1.00028.how many bright-dark-bright fringe shifts are observed as the cell fills with air?
