In the two-slit experiment, monochromatic light of wavelength 600 nm passes through a pair of slits separated by -5 2.20 × 10 m. What is the angle corresponding to the first bright fringe?

Using monochromatic light, an interference pattern is generated on a screen 50.0 cm away from a double slit. The width of the slit is 12 μm.  The third dark fringe is 6.0 cm from the center of the central maximum. What is the wavelength of the light used in nanometres?

Light of wavelength λ = 610 nm and intensity I0 = 240 W/m2 passes through a slit of width w = 4.8 μm before hitting a screen L = 1.6 meters away. Part (a) Use the small-angle approximation to write an equation for the phase difference, β, between rays that pass through the very top and very bottom of the slit when the rays hit a point y = 46 mm above the central maximum.   Part (b)  Calculate this phase difference, in radians?  Part (c)  What is the intensity of the light, in watts per square meter, at this point?

The intensity of the single-slit diffraction pattern at any angle 0 is given by 1 (0) = 1m (sing)². For light of wavelength 480 nm falling on a slit of width 3.5 µm, what is the value of a when 8 = 18°? 7.1 rad 0.31 rad 7.3 rad 2.3 rad 9.8 rad

What is the intensity fraction of a 500nm light that is incident on a double slit? Given that the slits have a width of 3µm, a slit seperation of 5µm, and an angle of 20 degrees.

In a double-slit experiment the distance between slits is 3.8 mm and the slits are 1.1 m from the screen. Two interference patterns can be seen on the screen: one due to light of wavelength 470 nm, and the other due to light of wavelength 570 nm. What is the separation in meters on the screen between the m = 3 bright fringes of the two interference patterns?

In a Young's double-slit experiment, a set of parallel slits with a separation of 0.108 mm is illuminated by light having a wavelength of 584 nm and the interference pattern observed on a screen 3.50 m from the slits. (a) What is the difference in path lengths from the two slits to the location of a third order bright fringe on the screen? answer in ?m (b) What is the difference in path lengths from the two slits to the location of the third dark fringe on the screen, away from the center of the pattern? answer in ?m

Which of these is the theoretical maximum number of bright fringes visible in the diffraction pattern when green (I = 500 nm) light shines through double slits separated by 2.1 * 10^-6m?

Hurry!!!

Light of wavelength 520 nm illuminates a slit of width 0.45 mm. (a) At what distance from the slit should a screen be placed if the first minimum in the diffraction pattern is to be 0.52 mm from the central maximum? 0.45 m 0.53 m 0.63 m 0.72 m (b) Calculate the width of the central maximum. 1.04 mm 2.08 mm 3.12 mm 4.16 mm
