Why do we use FM? Find Your Local Station: With AM radio, the amplitude, or overall strength, of the signal is varied to incorporate the sound information. With FM, the frequency (the number of times each second that the current changes direction) of the carrier signal is varied. FM signals have a great advantage over […]
Is all green glass uranium?
Is all green glass uranium? Perhaps the most reliable way to identify the presence of uranium in the glass is to expose it in the dark to a source of ultraviolet light (e.g., a black light). If the glass glows a rich green color, it contains uranium. Why is depression glass called depression? Depression glass […]

Which light is not seen from the Earth?
Which light is not seen from the Earth? What Does Invisible Light Do? Electromagnetic waves are all around us. This includes not only visible light, but also invisible ultraviolet and infrared rays. Infrared rays, with wavelengths longer than visible light, are also a familiar part of electrical appliances. Are there stars we Cannot see? All […]
How do you find the slope of a velocity time graph?
How do you find the slope of a velocity time graph? Using the Slope Equation Pick two points on the line and determine their coordinates. Determine the difference in y-coordinates for these two points (rise). Determine the difference in x-coordinates for these two points (run). Divide the difference in y-coordinates by the difference in x-coordinates […]
What is special about pea plants in genetics?
What is special about pea plants in genetics? To study genetics, Mendel chose to work with pea plants because they have easily identifiable traits (Figure below). As a result, one plant’s sex cells combine with another plant’s sex cells. This is called a “cross.” These crosses produce offspring (or “children”), just like when male and […]

Why is Jupiters spot red?
Why is Jupiters spot red? Hypotheses supported by laboratory experiments suppose that the color may be caused by chemical products created from the solar ultraviolet irradiation of ammonium hydrosulfide and the organic compound acetylene, which produces a reddish material—likely complex organic compounds called tholins. How long will the Great Red Spot last? He said the […]
