The mirror is carefully polarized to allow an image to transfer through the mirror, such that when the TV is off, the device looks like a mirror. [2] [3] Placement of a mirror TV is important to ensure both good mirror reflection and television picture quality.

Despite their relative rarity, the damage caused by EF5 tornadoes represents a disproportionate hazard to life and limb; since 1950 in the United States, only 59 tornadoes (0.1% of all reports) have been designated F5 or EF5, and yet these have been responsible for more than 1300 deaths and 14,000 injuries (21.5 and 13.6%, respectively).

There is a large difference in frame rate between film (24.0 frames per second) and NTSC (approximately 29.97 frames per second). Unlike the two other most common video formats , PAL and SECAM , this difference cannot be overcome by a simple speed-up , because the required 25% speed-up would be clearly noticeable.
