Two slides of length 12 cm are placed one on top of the other. A thin wedge of air is created between them by placing a thin piece of plastic under one end of the slide on top. When monochromatic, coherent light of wavelength 523 nm is incident on the slides from above, 8 dark bands per centimeter are observed. Calculate the thickness of the plastic. Answer in mm. Do not put units in the blank.

a, c, d, e are all applying about success strategies.

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.
