Assuming that the loop lies in the plane of this page, draw a diagram showing the loop, the area vector and magnetic field directed into the page. On your diagram above, draw the direction of the current as the magnetic field drops to zero in a time of 3.0 s. 9. You have 3 polarizers. The first is placed with its transmission axis horizontal. The second is placed with its transmission axis placed 45 degrees from the vertical, and the third is placed with its transmission axis placed 15 degrees from the vertical.
White light is incident along the curved edge of a piece of hemispherical glass block.
A larger circular screen is placed such that any light transmitted through the glass will land somewhere on the screen. The wavelength-dependent index of refraction for the glass is shown in the graph below. When driving at night on a highway outside the city, a car approaching you while moving the opposite direction appears as a single spot of light when it is a great distance away. Estimate the theoretical distance at which you could distinguish that there are two separate headlights on the car. Make sure to state what numbers you are assuming and what numbers you are estimating.
