How does Lene Hau slow down a beam of light? Hau and her team have previously shown that a Bose-Einstein condensate — which they make here by cooling sodium atoms to about 600 billionths of a degree (colder than deep space) — can slow down a light beam and even bring it to a standstill. […]
How do electromagnetic waves carry energy?
How do electromagnetic waves carry energy? In electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields. In sound waves, energy is transferred through vibration of air particles or particles of a solid through which the sound travels. What are the 6 common properties of electromagnetic radiation? Properties of Electromagnetic Radiation These magnetic […]
What does the inverse square law state?
What does the inverse square law state? Inverse Square law: The radiation Intensity is inversely proportional to the square of the distance. Notice in the diagram that as the distance doubles, the area quadruples and thus, the initial radiation amount is spread over that entire area and is therefore reduced, proportionately. What is a inverse […]

What are the two types of charge?
What are the two types of charge? Summary There are only two types of charge, which we call positive and negative. The vast majority of positive charge in nature is carried by protons, whereas the vast majority of negative charge is carried by electrons. Can we produce heat by using our hands? Answer: yes we […]
Why does the temperature of a substance not change when the phase changes?
Why does the temperature of a substance not change when the phase changes? But there is no temperature change until a phase change is complete. i.e. during phase change, the energy supplied is used only to separate the molecules ; no part of it is used to increase the kinetic energy of the molecules. So […]

What happens to the air pressure inside a balloon when the balloon is squeezed to half its volume at a constant temperature?
What happens to the air pressure inside a balloon when the balloon is squeezed to half its volume at a constant temperature? What happens to the air pressure inside a balloon when it is squeezed to half its volume at constant temperature? The atmospheric pressure decreases as they rise, so they expand. What causes pressure […]
