Water waves and sound waves are formed by vibrations in water and air respectively. These mechanical waves travel through the medium by causing... View Article
When an object is lifted the work is done against the gravity. When work is done on object energy is transferred to the object and it gains... View Article
In Einstein’s Special Theory of Relativity, Einstein concluded that time is relative, in other words, the rate at which time passes depends on... View Article
The magnetic field surrounding an inductor stores energy as current flows through the field. If the amount of current is slowly decreased, the... View Article
When light enters an array of equally-spaced identical slits, known as a diffraction grating, the bright fringes are formed due to constructive... View Article
In a power system, harmonics degrade the performance of the power system. The following are the disadvantages of harmonics: Harmonics increase... View Article
The frequencies which are 2, 4, 6, 8 times and so on multiplications of the main/root frequency are even harmonics. ODD harmonics are 3, 5, 7... View Article
The natural frequency of the object or an instrument has its own natural frequency and produces its own characteristic vibrational mode or... View Article
General relativity is a field theory because Einstein’s field equation is an equation of motion for the field at each point in time is determined... View Article
There are no categorical antonyms for quantum physics, however quantum physics is defined as the branch of physics that is concerned with the... View Article
Vacuum energy is underlying background energy that exists in space throughout the entire Universe. Not much has been studied about these fleeting... View Article
The strongest intermolecular forces are dipole-dipole interactions. A dipole-dipole force is when the positive side of a polar molecule attracts... View Article
Standard temperature and pressure defined to be 0 degrees Celsius and 1 atm pressure describes standard conditions and is used to measure gas... View Article
“Standard temperature and pressure are standard sets of conditions for experimental measurements to be established to allow comparisons to be... View Article
Fresnel diffraction occurs when the distance from the obstruction to the screen or the distance from the screen to the obstruction is comparable... View Article
Light is an electromagnetic wave that doesn’t need a medium to propagate. The strength of the wave, however, can get weaker with the distance,... View Article
There are two theories of light. In the seventeenth century, two contradicting theories of the nature of light were proposed: wave theory and the... View Article
The diffraction of waves is the phenomenon in which the waves spread out as they pass through an aperture or around objects. Diffraction occurs... View Article
