Two thin slits separated by 0.0634 mm are illuminated by light from a He-Ne laser (? = 633 nm), producing interference fringes on a distant screen. Find the angle between the centers of the central bright fringe and the next bright fringe.

Given:

distance between the slits d = 0.0634 mm

= wavelength of the He-Ne laer (?) = 633 nm

= 633*10^-9 m

......................................................................................................

bright fringes are at an angle from the central bright fringe

? = sin-1 (2?/d) ...... (1)

plug the values in equation 1 we have

? = sin^-1 (2*633*10^-9 m /0.0634*10^-3 m )

= 1.140

Light from a red laser (650 nm) is incident on two slits separated by 0.5 mm. Each slit is 0.25 mm wide. Quantitatively sketch the pattern you would observe on a screen that is located 2.0 m from the slits. Your sketch should range from -10 mm to 10 mm and include only the fringes you would observe. (Label the locations of the fringes) PLEASE EXPLAIN THOROUGHLY!!!!

Light of wavelength 600 nm passes though two slits separated by 0.25 mm and is observed on a screen 1.3 m behind the slits. The location of the central maximum is marked on the screen and labeled y = 0. A .At what distance, on either side of y = 0, are the m = 1 bright fringes? B.A very thin piece of glass is then placed in one slit. Because light travels slower in glass than in air, the...

Suppose that you shine light from a laser through two slits that are placed one in front of the other, separated by 0.6mm. The width of each slit is 0.12mm. The light will travel from the laser, through the slits, and onto a screen 1.5m away. a. Predict what you will observe on the screen, and compare it to what you would expect from single-slit diffraction. b. If ray (geometrical optics) accurately described this siutation, what would the pattern on...
