The ceiling of your lecture hall is probably covered with acoustic tile, which has small holes separated by about 6.9 mm. using light with a wavelength of 579 nm, how far could you be from this tile and still resolve these holes? the diameter of your eye is about 5 mm.

( )m

could you resolve these holes better with red light or with violet light? (you have only 1 try.)

1. violet.

2. red

d they tend to lose electrons and become cations.

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.
