In a single-slit experiment, the slit width is 170 times the wavelength of the light. What is the width (in mm) of the central maximum on a screen 2.4 m behind the slit?

= 28 mm

Explanation:

Displacement from the central maximum to minimum is as deterrmined as follows;

=

If first minimum (m) = 1

single- Slit width is 170 times the wavelength of the light.

i.e

a = 170 λ

 =

 = 0.014 m

width of the central maximum can now be determined as:

=

= 2(0.014 m)

= 0.028 m

= 28 mm

Hence, the width (in mm) of the central maximum on a screen 2.4 m behind the slit

= 28 mm

  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.
