The directions are perpendicular. The directions are parallel for one polarization, perpendicular for the other. None of the above. Upright, enlarged, and real Upright, smaller, and virtual Inverted, enlarged, and virtual Inverted, smaller, and real A spectrum is produced by a glass prism because some colors have a greater change in speed than others as they enter the glass. All of the above contribute to the creation of the spectrum.
Light is said to be unpolarized if the direction of the electric field changes rapidly and randomly.
The frequency of the wave changes rapidly and randomly. All of the above must be true for light to be unpolarized. To correct farsightedness, use a converging lens to form a real image a converging lens to form a virtual image a diverging lens to form a real image a diverging lens to form a virtual image Light passes through a double slit and the interference pattern is viewed on a screen. At a particular point on the screen, the part of the wave passing through one slit arrives one wavelength behind the part of the wave that passed through the other slit. This point on the screen is bright dark neither very bright nor very dark the distance between the slits needs to be known to determine whether it is bright, dark, or in between.
