Asked by Hana
Two slits are made 1mm apart and the screen is placed 1m away. What is the fringes separation when blue -green light of wavelength 500nm is use?

We can use the formula for fringe separation:
fringe separation = (wavelength x distance to screen) / distance between slits
Plugging in the values:
fringe separation = (500nm x 1m) / 0.001m
fringe separation = 500,000nm / 0.001m
fringe separation = 500,000,000nm/m
fringe separation = 500,000,000 m⁻¹
Therefore, the fringe separation is 500,000,000 m⁻¹ (or 0.5 mm⁻¹).
