Two narrow and parallel slits are 0.50 mm apart. a light beam in air consisting of two frequencies 6.67 x 1014 hz (blue) and 4.50 x 1014 hz (red) is shone on the slits and an interference pattern is formed on a screen 1.50 m away. (a) how far apart (in mm) are the 3rd bright fringe above the central bright fringe for blue and the 2nd dark fringe below the central bright fringe for red? (b) what are the widths of the central bright fringes of blue and red?

answer: a. same unit

explanation:

conservation of mass

mass before something happens = mass afterwards

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
