Light from a helium-neon laser (A = 633 nm) is used to illuminate two narrow slits. The interference pattern is observed on a screen 3.3 m behind the slits. Twelve bright fringes are seen, spanning a distance of 54 mm .

Two slits are separated by 0.20 mm and produce an interference pattern. The fifth maximum is 12.8 cm from the central maximum. The wavelength of the light used is 550 nm. Determine the distance at which the screen is place

Coherent light that contains two wavelengths, 660 nm (red) and 470 nm (blue), passes through two narrow slits that are separated by 0.460 mm. Their interference pattern is observed on a screen 4.00m fromthe slits. What is the distance on the screen between the first - order bright fringes for the two wavelength?

How far is the second dark fringe to the right of the central bright fringe in the double-slit interference pattern seen on a screen 5 m from the slits? The slits are separated by 0.2 mm and are illuminated by monochromatic light of wavelength 548 nm.

Two narrow slits separated by 0.43 mm are illuminated by monochromatic light of wavelength 410 nm. How many bright fringes can be seen on a screen 1.2 cm wide placed 1.4 m in front of the slits?

White light falls on two narrow slits separated by 0.48 mm. The interference pattern is observed on a screen 6.0 m away. (a) What is the separation (in mm) between the first maxima for red light (2 = 700 nm) and violet light (4 = 400 nm)? mm (b) At what point (in degrees) nearest the central maximum will a maximum for yellow light (A - 600 nm) coincide with a maximum for violet light? Identify the order for each maximum. myellow mviolet

In the figure, a broad beam of light of wavelength 628 nm is sent directly downward through the top plate of a pair of glass plates touching at the left end. The air between the plates acts as a thin film, and an interference pattern can be seen from above the plates. Initially, a dark fringe lies at the left end, a bright fringe lies at the right end, and nine dark fringes lie between those two end fringes. The plates are then very gradually squeezed together at a constant rate to decrease the angle between them. As a result, the fringe at the right side changes between being bright to being dark every 16.3 s. (a) At what rate is the spacing between the plates at the right end being changed? (b) By how much has the spacing there changed when both left and right ends have a dark fringe and there are five dark fringes between them? Incident light TTT (a) Number Units (b) Number Units

Two narrow slits separated by 0.42 mm are illuminated by monochromatic light of wavelength 642 nm. How many bright fringes can be seen on a screen 1.1 cm wide placed 1.8 m in front of the slits?

Light of wavelength 740.0 nm passes through a single slit of width 1.95 µm, and a diffraction pattern is observed on a screen 25.5 cm away. Determine the relative intensity of light I/Imax at 14.0 cm away from the central maximum.

The light emitted by a helium-neon laser (λ = 633 nm) illuminates two slits spaced by 0.40 mm. A viewing screen is located 2.0m behind the cracks. What are the distances between the two bright fringes of order m = ±2 and between the dark fringes of the same order?
