At most, how many bright fringes can be formed on either side of the central bright fringe when light of wavelength 579 nm falls on a double slit whose slit separation is 3.64 x 10-6 m? Number i Units

You have been asked to measure the width of a slit in a piece of paper. You mount the paper 80.0 centimeters from a screen and illuminate it from behind with laser light of wavelength 633 nanometers (in air). You mark two of the intensity minima as shown in the figure, and measure the distance between them to be 17.9 millimeters. (Figure 1) What is the width a of the slit?

The figure below gives ẞ versus the sine of the angle in a double-slit interference experiment using light of wavelength 500. nn What is the slit separation (in μm)? ẞ (rad) 30.0 20.0 10.0 0.5 1 sine

Light with a wavelength of 495 nm strikes a single slit that is 0.6 mm wide. The diffraction pattern produced by the slit is observed on a wall at a distance of 2.5 m from the slit. a) Calculate the distance from the center of the pattern to the first dark fringe. a) Calculate the distance from the center of the pattern to the second dark fringe.

A thin film of thickness 1.5 µm is placed in Michelson interferometer which causes a 7.5 fringe shift in the interference pattern. The film is removed and replaced with another made of the same material which causes a shift of 9.0 fringes. Both shifts are relative to the pattern when no film was inserted. What is the thickness (um) of the second film? O 1.3 O 0.8 O 2.2 O 1.5 O 2.5 O 1.8 O 2.0 O 0.6 O 2.7 O 1.1

A light with wavelength λ = 580 nm falls on a pair of closely separated slits. The first dark fringe of the interference pattern is at an angle θ = 7.75 degrees from the central maximum. a) Express the separation between the slits in terms of θ and λ.  b) Solve for the numerical value of d in mm.

Light of wavelength 632 nm passes through a slit 7.00 × 106 m wide and falls on a screen that is 2.19 m away. What is the distance on the screen from the center of the central bright fringe to the third dark fringe on either side? Number i 0.5 Units m

Two narrow slits are 0.05mm apart. The dark fringe of order 10 is 0.5 degrees from the central bright fringe. What is the wavelength of the light? nm

Problem 2: Light of wavelength 685 nm shines through two narrow slits. When the interference pattern appears on a wall that is 2.50 meters away, the first bright fringe is 0.75 centimeters from the central bright spot. a) Calculate the distance between the two slits. b) If another light source has its first bright fringe only 0.69 centimeters from the central bright spot under the same experimental conditions, calculate the wavelength of this new light source.

OResources You illuminate a slit with a width of 73.5 µm with a light of wavelength 735 nm and observe the resulting diffraction pattern on a screen that is situated 2.87 m from the slit. What is the width, in centimeters, of the pattern's central maximum? cm width:
