Question
A double-slit interference experiment is performed with two verynarrow slits separated by 0.10 mm. Theexperiment uses red light with a wavelength of 670 nm and projects the interference pattern ontoa screen 10.0 m away from the slits. (a) What is the distance between two nearbybright fringes on the screen?1 m
(b) What is the distance between two nearby dark fringes on thescreen? Assume these fringes are all near =0.
2 m (a) What is the distance between two nearbybright fringes on the screen?
1 m
(b) What is the distance between two nearby dark fringes on thescreen? Assume these fringes are all near =0.
2 m
Explanation / Answer
Slit separation d = 0.1 * 10 ^ -3 m
Wavelength = 670 * 10^-9 m
