3. How close together were you able to make your slits? In other words, calculate the quantity d in the relation Δy = (wavelength)L/d .

Between slits there is 0.5 cm

I believe Δy is referred to how far apart the bright spots were front each other. so 0.10m / 5

Double Slit Experiment Data

Wavelength (nm)

650 nm

Distance from foil to wall (m)

1.5 m

Number of bright spots

5

Distance between first and last bright spot (m)

0.10m

In a double-slit experiment, the distance between slits is 0.5.0 mm and the slits are 2.0 m from the screen. Two interference patterns can be seen on the screen: one due to light of wavelength 480 nm, and the other due to light of wavelength 600 nm. What is the separation on the screen between the second -order (m = 3) bright fringes of the two interference patterns?(show the ray diagrams)

Consider a source of light with wavelength λ = 490 nm that shines on two identical narrow slits. The slits are separated by a distance a = 30 μm. An interference pattern is observed on a screen located a distance L away from the slits. On the screen, the location of the second dark spot to the left of the central bright spot is found to be y = 1.2 cm from the central bright spot. Let this particular position...

Blue light of wavelength 470 nm is used to illuminate a pair of narrow slits that are 0.020 mm apart and 1.60 m from a screen. What is the angular position of the second-order minimum (dark spot)? What is the distance on the screen between the central maximum and the second-order minimum? The reason there is a dark spot at this location on the screen is because light from one slit has to travel further than light from the other...
