The index of refraction for violet light in silica flint glass is 1.66, and that for red light is 1.62. what is the angular spread (in degrees) of visible light passing through a prism of apex angle 60.0° if the angle of incidence is 54.0°? see figure below. a triangular prism is shown. a ray of visible light moves up and to the right and is incident on the left edge of the prism. inside the prism a rainbow of colors spreads out from the incident ray and in order from top to bottom they are red, orange, yellow, green, blue and violet. once the rainbow leaves the prism, it continues to move down and to the right but all the colors are at slopes which are steeper than they were within the material. the rainbow is then projected onto a screen. the angular spread between the red and violet colors is indicated. a dashed line extends from the incident ray on the left to the right and the angle that this line makes with the red light ray is labeled deviation of red light. ° (b) what if? what is the maximum angular spread (in degrees) for white light passing through this prism?

Certain bacteria (such as aquaspirillum magnetotacticum) tend to swim toward the earth’s geographic north pole because they contain tiny particles, called magnetosomes, that are sensitive to a magnetic field. if a transmission line carrying 100 a is laid underwater, at what range of distances would the magnetic field from this line be great enough to interfere with the migration of these bacteria? (assume that a field less than 5% of the earth’s field would have little effect on the bacteria. take the earth’s field to be 5.0 * 10-5 t, and ignore the effects of the seawater.)
