What is the purpose of a spectrograph? A spectrograph is an instrument that separates incoming light by its wavelength or frequency and records the resulting spectrum in some kind of multichannel detector, like a photographic plate. Many astronomical observations use telescopes as, essentially, spectrographs. What are spectral features of an image? Spectral features of images, […]
What is the moral of the story Frankenstein?
What is the moral of the story Frankenstein? One message conveyed by Frankenstein is the danger that lies with considering the negative consequences of science and technology after-the-fact, instead of before.

Can light be a reference frame?
Can light be a reference frame? In all reference frames that actually exist, light travels through space and time in a normal way just like any other object. According to Special Relativity, as a frame goes faster, it shortens more in the direction of motion, relative to the stationary observer. How did Einstein know that […]

What frequency makes you smarter?
What frequency makes you smarter? The highest frequency brain waves are apparently called gamma waves. These waves can have a frequency of anywhere between 25 and 100 Hz. People whose brains produce more gamma waves are said to have greater ability to concentrate, focus and experience higher levels of cognition. Will reading increase IQ? It […]
What are 2 examples of mechanical waves?
What are 2 examples of mechanical waves? A sound wave is an example of a mechanical wave. Sound waves are incapable of traveling through a vacuum. Slinky waves, water waves, stadium waves, and jump rope waves are other examples of mechanical waves; each requires some medium in order to exist. Who discovered scalar waves? Heinrich […]

How does the shockwave of an explosion kill?
How does the shockwave of an explosion kill? Blast Effects Most damage comes from the explosive blast. The shock wave of air radiates outward, producing sudden changes in air pressure that can crush objects, and high winds that can knock objects down. For the most part, a nuclear blast kills people by indirect means rather […]
