Light of wavelength 633 nm is incident on a narrow slit. The angle between the first diffraction minimum on one side of the central maximum and the first minimum on the other side is 1.20°. What is the width of the slit?

Light with wavelength å passes through a narrow slit of width w and is seen on a screen which is located at a distance D in front of the slit. The first minimum of the diffraction pattern is at distanced from the middle of the central maximum. Calculate the wavelength of light if VAD. Give your D=1.3 m, d=1 mm and w = answer in nanometers.

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

The first two dark fringes on the same side of the central maximum in a single-slit diffraction pattern are 1.0 cm apart (center to center). The wavelength of the light is 530 nm and the screen where the pattern is formed is 2.5 m from the slit. What is the slit width?

A diffraction grating has 2500 lines/cm. What is the angle between the first-order maximum for red light wavelentgh = 680 nm and the first-order maximum for blue light wavelength = 410 nm?

Light with a wavelength of 633 nm goes through a narrow slit. The angle between the first minimum on one side of the central maximum and the first minimum on the other side is 1.2o. What is the width of the slit?

A single slit of width 2.4 um (micrometers) is illuminated by red light of wavelength 700 nm (nanometers). A screen is placed 4.0 m beyond the slit. a) What is the linear width (edge to edge) of the central diffraction maximum that appears on the screen? b) What is the linear width of the first maximum to the side of the central one?

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?

An instructor directs monochromatic light toward a single slit in an opaque barrier. The light has a wavelength of 550 nm and the slit is 0.225 mm wide. The light that passes through the slit creates a diffraction pattern on a screen, which is 1.20 m from the slit. (a) How wide (in mm) is the central maximum (the central, bright fringe), as measured on the screen? mm (b) How wide (in mm) is either of the two first-order bright fringes, as measured on the screen? mm

A laser beam is normally incident on a single slit with width 0.580 mm. A diffraction pattern forms on a screen a distance 1.20 m beyond the slit. The distance between the positions of zero intensity on both sides of the central maximum is 2.12 mm. Calculate the wavelength of the light (in nm). X Find the relationship among y, the distance from the central maximum to the first minimum, L, and 0, and then apply the equation for the Fraunhofer diffraction pattern. Solve for A. Hint: use a small-angle approximation. nm
