Scientists describe a wave using many properties. These properties include amplitude, frequency and wavelength. Amplitude - The measure of the... View Article
The escape velocity of Earth is 11.19 km/s. Escape velocity is the minimum speed needed for a free object that is non-propelled to escape from... View Article
Two waves are considered coherent sources if they emit light waves of the same frequency and nearly equal amplitude and are always in phase with... View Article
For waves such as visible light that has high frequency, stimulated emission is the most effective way of creating coherent beams. But for waves... View Article
Orbital velocity is the velocity at which a body revolves around the other body. The orbital velocity can be calculated using the following... View Article
A Van de Graaff generator is an electrostatic generator, invented by an American physicist Robert J. Van de Graaff. It uses a moving belt that... View Article
Escape velocity is the minimum velocity required by a body to be projected to overcome the gravitational pull of the earth. The escape velocity... View Article
Coherent sources are sources of light that emit waves which have zero or constant phase difference and same frequency. Incoherent sources are... View Article
The orbital velocity of Jupiter is 13.07 km/s. In the solar system, mercury has the fastest orbital speed and Neptune has the lowest orbital speed.... View Article
When the oscillator motion reduces due to an external force, the oscillator and its motion are said to be damped. The energy of the oscillator,... View Article
Ohm’s law is an important law in electric circuits that describe the relationship between current, voltage and resistance. Ohm’s law can be used... View Article
The light emitted from an LED is neither monochromatic nor spectrally coherent. However, the spectrum of an LED light is sufficiently narrow that... View Article
No, not all oscillatory motion is simple harmonic motion. Oscillatory motion means that the motion is periodic. It has the following form:... View Article
Following are the main characteristics of simple harmonic motion: In simple harmonic motion, the acceleration of the particle is directly... View Article
