How long do atoms live for? For carbon-14, this number is 5,730 years. For different radioactive atoms, this number can be anywhere from a tiny fraction of a second to minutes, hours, days, or even millions of years. But, in all these cases, the point of the decay is to reach a type of atom […]

What makes a real image?
What makes a real image? A real image occurs where rays converge, whereas a virtual image occurs where rays only appear to diverge. Real images can be produced by concave mirrors and converging lenses, only if the object is placed further away from the mirror/lens than the focal point, and this real image is inverted. […]

Which is the densest of all layers?
Which is the densest of all layers? inner core What are the 4 layers of earth? Starting at the center, Earth is composed of four distinct layers. They are, from deepest to shallowest, the inner core, the outer core, the mantle and the crust. Except for the crust, no one has ever explored these layers […]
What are the sources of error in this experiment?
What are the sources of error in this experiment? You are measuring against a standard, using an instrument that can never perfectly duplicate the standard, plus you’re human, so you might introduce errors based on your technique. The three main categories of errors are systematic errors, random errors, and personal errors. What is meant by […]
What are the negative effects of the atmosphere?
What are the negative effects of the atmosphere? Acid rain, climate change and smog all damage the Earth surface. Contaminated water and gases seep into the earth, changing the composition of soils. That directly affects agriculture, changing crop cycles and the composition of the food we all eat. How do humans affect the atmosphere? Humans […]

Why do the two slits need to be small in order for an interference pattern to occur?
Why do the two slits need to be small in order for an interference pattern to occur? The very short wavelengths of visible light explain why interference effects are observed only in special circumstances—the spacing between the sources of the interfering light waves must be very small to separate regions of constructive and destructive interference. […]
