Light of wavelength 5. 6×10−7m passes through two parallel slits and falls on a screen 4. 5 m away. Adjacent bright bands of the interference pattern are 2. 2 cm apart.
Part A
Find the distance between the slits.
Express your answer to two significant figures and include the appropriate units.
d = Part B
The same two slits are next illuminated by light of a different wavelength, and the fifth-order minimum (m = 5)for this light occurs at the same point on the screen as the fourth-order minimum (m = 4) for the previous light. What is the wavelength of the second source of light?
Express your answer to two significant figures and include the appropriate units.
λ =
