Aphysics instructor wants to produce a double-slit interference pattern large enough for her class to see. for the size of the room, she decides that the distance between successive bright fringes on the screen should be at least 3.00 cm. if the slits have a separation d=0.0175mm, what is the minimum distance from the slits to the screen when 632.8-nm light from a he-ne laser is used?

0.83 m

Explanation:

w = distance between successive bright fringes = 3.00 cm = 0.03 m

d = separation between the slits = 0.0175 mm = 0.0175 x 10⁻³ m

λ = Wavelength of the light from He-Ne laser = 632.8 x 10⁻⁹ m

D = distance of the screen from the slits  = ?

Distance between successive bright fringes is given as

Inserting the values

D = 0.83 m

the assestment will probley apele with cause and effect

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
