In a Young's double slit experiment, if the separation between the two slits is 0.050 mm and the distance from the slits to a screen is 2.5 m,
 
  find the spacing between the first-order and second-order bright fringes for light with wavelength of 600 nm.
  A)
 
  1.5 cm
  B)
 
  3.0 cm
  C)
 
  4.5 cm
  D)
 
  6.0 cm
  E)
 
  9.0 cm

Question 2

The velocity of a mass attached to a spring is given by v = (1.5 cm/s) sin(t + /2 ), where  = 3.0 rad/s. What is the corresponding expression for x?
 
  A)
 
  x = -(4.50 cm) sin(t + /2 )
  B)
 
  x = (4.50 cm) cos(t + /2 )
  C)
 
  x = -(0.50 cm) cos(t - /2 )
  D)
 
  x = -(0.50 cm) cos(t + /2 )
  E)
 
  x = -(0.50 cm) sin(t + /2 )
