Question

White light falls on two narrow slits separated by 0.60 mm. The interference pattern is observed on a screen 3.2 m away.

(a) What is the separation (in mm) between the first maxima for red light (λ = 700 nm) and violet light (λ = 400 nm)?

(b) At what point (in degrees) nearest the central maximum will a maximum for yellow light (λ = 600 nm) coincide with a maximum for violet light?

Identify the order for each maximum.

m_yellow =

m_violet =
