Question

16.)The graph shows the light intensity on a screen Intensity behind a 0.2-mm-wide slit illuminated by light with a 500 nm wavelength. a. Draw a picture in the box of how a photograph A 500 nm taken at this location would look. Use the same horizontal scale, so that your picture aligns with the graph above. Let the white of the paper represent the brightest intensity and the darkest you can draw with a pencil or pen be the least intensity. b. Using the same horizontal scale as in part a, Intensity λ=250 nm draw graphs showing the light intensity if a 0.2 mm ii. λ = 1000 nm, a = 0.2 mm. iii. A 500 nm, a 0.1 mm. iv. 500 nm, Intensity λ-1000 nm a-0.4 mm. a 0.2 mm Intensity λ=500 nm a=0.1 mm Intensity A 500 nm a 0.4 mm

Answer 1

16. The graph shows the light intensity on a screen behind a 0.2 mm wide slit illuminated by light with a 500 nm wavelength.

(a) Draw a picture in the box of how a photograph taken at this location would look.

(b) Using the same horizontal scale in part (a), draw graphs which showing the light intensity if

i. $\lambda$ = 250 nm and a = 0.2 mm

ii. $\lambda$ = 1000 nm and a = 0.2 mm

iii. $\lambda$ = 500 nm and a = 0.1 mm
