What happens if index of refraction is less than 1? Refractive indices less than 1 can occur and if the phase velocity of the light in the medium is faster than the speed of light. Negative refractive indices can occur if both the permittivity and permeability of the material are both negative at the same […]

What does dead animal give us?
What does dead animal give us? Carcasses not only provide food for carrion-eating animals. Their nutrients also increase the growth of surrounding plants, which attracts many herbivorous insects and their predators. Which animal eats dead human bodies from graves? Examples of carrion-eaters (or scavengers) include vultures, condors, hawks, eagles, hyenas, Virginia opossum, Tasmanian devils, coyotes […]
Who introduced K method?
Who introduced K method? K-theory was invented in the late 1950s by Alexander Grothendieck in his study of intersection theory on algebraic varieties. What is substitution math? In Algebra “Substitution” means putting numbers where the letters are: When we have: x. − 2. How do you find y using substitution? The first equation tells you […]
What is wrong with the steady state theory?
What is wrong with the steady state theory? In the Steady State the Universe was always the same so it never produced a blackbody. Hence the existence of a blackbody background ruled out the Steady State. In addition, the temperature of the cosmic background can be measured in some very distant clouds that produce absorption […]
What do you call the highest of a wave?
What do you call the highest of a wave? The highest surface part of a wave is called the crest, and the lowest part is the trough. The vertical distance between the crest and the trough is the wave height. The horizontal distance between two adjacent crests or troughs is known as the wavelength. What […]
Is elevation based on sea level?
Is elevation based on sea level? Sea level is the base level for measuring elevation and depth on Earth. Because the ocean is one continuous body of water, its surface tends to seek the same level throughout the world. Just like the ocean, the elevation of land may rise and fall over time. How do […]
