In Youngs double slit experiment the distance between the screen and the slits is 1.00 m. The slits separation is 0.050 mm and the distance between the central bright and first order bright is found to be 8.00 mm. Calculate the wavelength of the light used.

Which of the following correctly describes what happens when an atomic bomb explodes? small pieces of fissionable material are joined and form a body with a mass greater than the critical mass, the relative number of neutrons escaping decreases, and a chain reaction and explosion result. large pieces of fissionable matter are brought together quickly and form a body with a mass smaller than the critical mass, the relative number of escaping neutrons increases, and a chain reaction and explosion result.
