Monochromatic light with a wavelength of 600 nanometers (one nanometer is 10-9 meters) is incident upon a double slit arrangement. The interference fringes are seen on a screen that is 10 m from the slits. If the bright fringes are 5 mm apart, what is the slit separation; that is, what is the value of d? Hint: convert all of the values into meters first.

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
