A diver shines a flashlight upward from beneath the water (n=1.33) at an angle of 23.3° to the vertical. At what angle does the light refract through the air above the surface of the water?

b. latent learning (the word "latent" itself means something that exists but isn't obvious, only under certain conditions! )

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.
