Aray of monochromatic light traveling through the air is incident on the surface of a crown glass block at an angle of 45°. assuming the monochromatic light is one of the colors below, which one would have the smallest angle of refraction?

atomic = no of protons.

mass number-atomic number = neutron number

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.
