1、1 In a double-slit experiment the distance between the slits is 5.0 mm and the slits are 1.0 m from the screen. Two interference patterns can be seen on the screen: one due to light with wavelength 480 nm and the other due to light with wavelength 600 nm. What is the separation on the screen between

2、 the third-order bring fringes of the two interference patterns?Solution2 S1 and S2 are identical radiators of waves that are in phase and of the same wavelength . The radiators are separated by distance d=3.0 . Find the greatest dista-nce form S1, along the x axis, for which fully destructive inter

3、ference occurs. When m=0, x has the greatest value 3 A plane monochromatic light wave in air is perpendicularly on a thin film of oil that covers a glass plate. The wavelength of the source may be varied conti-nuously. Fully destructive interference of the reflected light is observed for wavelengths

4、 of 500 nm and 700 nm and for no wavelength between. The index of the glass is 1.50. show that the index of refraction of the oil must be less than 1.50.If Since fully destructive interference does not occur for any wavelengths between nm and nmBecause n is integer, thus the assumption is not correc

5、t. 4 In a Newtons rings experiment, the radius of curva-ture R of the lens is 5.0 m and the lens diameter is 20 mm. (a) How many bright fringes are produced? Assume that l=589 nm. (b) How many bright fring-es would be produced if the arrangement were immersed in water?Thus we can see 34 bright fring

6、eswaterThus we can see forty-fifth bright fringes.5 A Newtons rings apparatus is to be used to determine the radius of a lens. The radii of the nth and (n+20)th bright rings are measured and found to be 0.162 and 0.368 cm. in light of wavelength 546 nm. Calculate the radius of curvature of the lower

7、 surface of the lens.6 If mirror M2 in a Michelson interference is moved through 0.233 mm, a shift of 792 fringes occurs. What is the wavelength of the light producing the fringe pattern?7 An airtight chamber 5.0 cm long with glass windows is placed in one arm of a Michelson interferometer . Light wavelength l=500 nm is used. Evacuated the air from the chamber causes a shift of 60 fringes. From this da
