The slits have a separation of 0.3050 mm, and the second-order maximum occurs at an angle of 0.203° from the central maximum.

Question

physics could u please help me I need help with my physics hw due tomorrow

Answer 1

(a)

 

nλ = d sinθ ⇒

 

λ = d sinθ / n = (0.3050 x 10^-3 m) sin(0.203°) / 2 = ? meters

 

(b)

 

θ = sin^-1(nλ/d) 

 

n = 3

You know λ from part (a)

You have d

 

Just plug in the numbers.

 

(c)

 

Work the same way as (b), but with n = 4
