Can you see atoms using a scanning tunneling microscope? No one has ever seen an atom. The wavelength of visible light is more than 1000 times bigger than an atom, so light cannot be used to see an atom. Scanning Tunneling Microscopes work by moving a probe tip over a surface we want to image. […]
What are three sources of geothermal energy?
What are three sources of geothermal energy? Geothermal energy finds its way to the earth’s surface in three ways: Volcanoes and fumaroles (holes in the earth where volcanic gases are released) Hot springs. Geysers. How deep do you have to go for geothermal? For a horizontal loop you only need to dig between 6 – […]

Does yellow light have a higher frequency than blue?
Does yellow light have a higher frequency than blue? So red light vibrates at about 400 million million cycles per second. Fast! Higher frequency (with shorter wavelength) has more energy: Red light has lower frequency, longer wavelength and less energy….Visible Spectrum. Color Wavelength Range (nm) Yellow 570–590 Green 495–570 Blue 450–495 Violet 380–450 Does yellow […]
What are the three categories of sound?
What are the three categories of sound? The three basic categories of sound are dialogue, music, and sound effects. Dialogue is “characters talking to one another in films” (Goodykoontz &Jacobs, 2011). How do you explain sound to a child? These sound waves are formed by objects vibrating (shaking back and forth). Sound waves travel through […]

Is 1.21 gigawatts alot?
Is 1.21 gigawatts alot? Sure, that’s a lot of power but actually not a lot of energy. 1.21 gigawatts delivered in 50 microseconds is only about 60,500 Joules, or 14 kilocalories of energy. Which is the amount of energy in…a cucumber. Is it possible to get 1.21 gigawatts? To get 1.21GW you would therefore require […]
