Explanation / Answer

4. for the formula

m*lambda = d*sin(theta)

d represents the slit width

hence b. width of an idividual slit

5. as we can see, point A is the brightest so it is the first order maxima

hence a. A

6. given, 1/a = 5 / mm

a = 1 mm / 5 = 0.2 mm = 0.2*10^-3 m

7. given n = 600 lines / mm

so slit width a = 1/n = 1 mm/600 = 1.666*10^-6 m

8. when valence electron moves from lower state to higher state,. light is absorbed as it absorbs energy and does not release it instedf

so False
