George JacksonA sound wave is the pattern of disturbance caused by the movement of energy traveling through a medium (such as air, water or any other liquid or solid matter) as it propagates away from the source of the sound. Sound waves are created by object vibrations and produce pressure waves, for example, a ringing cellphone. … Read more
vector operations, Extension of the laws of elementary algebra to vectors. They include addition, subtraction, and three types of multiplication. The sum of two vectors is a third vector, represented as the diagonal of the parallelogram constructed with the two original vectors as sides. What are the 3 types of vectors in physics? Zero Vector. … Read more
Ultrasound is an imaging technique where high-frequency sound waves (2-15MHz) are used to generate an image. An ultrasound wave is produced by a probe using the piezoelectric effect: Certain crystalline structures will vibrate at a particular frequency when a certain voltage is applied across them. How is physics used in ultrasound? The crucial physics principles … Read more
One way to calculate mass: Mass = volume × density. Weight is the measure of the gravitational force acting on a mass. What is total mass in physics? Mass is a combination of the total number of atoms, the density of the atoms, and the type of atoms in an object. How to Measure Mass. … Read more
These units are known as derived units. There are seven base units measurements namely meter, kilogram, second, ampere, kelvin, mole, and candela. The most common among these are kilograms, seconds, and meters. What are the units of measurement in physics? The base SI units are metre, kilogram, second, kelvin, ampere, candela and the mole and … Read more
Vectors are used to represent physical quantities that have a magnitude and direction associated with them. For example, The velocity of an object is a vector. The direction of the vector specifies the direction of travel, and the magnitude specifies the speed. The force acting on an object is a vector. What is the I … Read more
Zero Vector. Unit Vector. Position Vector. Co-initial Vector. Like and Unlike Vectors. Co-planar Vector. Collinear Vector. Equal Vector. What is a vector in physics? A vector is a quantity or phenomenon that has two independent properties: magnitude and direction. The term also denotes the mathematical or geometrical representation of such a quantity. Examples of vectors … Read more
Vacuum cleaners work because of Bernoulli’s Principle, which states that as the speed of air increases, the pressure decreases. Air will always flow from a high-pressure area to a low-pressure area, to try to balance out the pressure. What is a technology vacuum? Vacuum technology is a method used to evacuate air from a closed … Read more
Light waves have two important characteristics known as wavelength and frequency. The distance between the peaks of the wave is known as the wavelength. In the case of a light wave, the wavelengths are in the order of nanometers. Frequency is the number of waves crossing past a point in a second. What is wave … Read more
Newton’s corpuscular theory. Huygen’s wave theory. Maxwell’s electro magnetic wave theory. Planck’s quantum theory. What is the wave theory of light? Wave theory speculates that a light source emits light waves that spread in all directions. Upon impacting a mirror, the waves are reflected according to the arrival angles, but with each wave turned back … Read more
