# What is a phase class 11?

Phase of a wave describes the state of motion as the wave sweeps through an element at a particular position. In-phase– Two points are said to be in-phase with each other when these two points are at the same position and they both are doing the same thing i.e. both the two points are exhibiting the same behaviour.

## What is phase 11 Physics difference?

The phase difference is the difference in the phase angle of the two waves. Path difference is the difference in the path traversed by the two waves. The relation between phase difference and path difference is direct. They are directly proportional to each other.

## What is the phase φ?

Φ (phi) – is the phase angle in degrees or radians that the waveform has shifted either left or right from the reference point.

## What is phase angle in Physics 11?

Phase angle refers to a particular point in the time of a cycle whose measurement takes place from some arbitrary zero and its expression is as an angle. Furthermore, a phase angle happens to be one of the most important characteristics of a periodic wave.

## What is a phase in physics?

In Physics, the phase is defined as the position of a point in time on a cycle of a waveform. A complete cycle that is 360 degrees is defined as the phase. The phase is expressed in terms of radians. One radian of phase is 57.3 degrees approximately.

## What do you mean by phase?

1 : a step or part in a series of events or actions : stage I have completed the first phase of my training. 2 : the way that the moon or a planet looks to the eye at any time in its series of changes with respect to how it shines The new moon and the full moon are two phases of the moon. phase. noun.

## What is phase of a wave?

If the crests of two waves pass the same point or line at the same time, then they are in phase for that position; however, if the crest of one and the trough of the other pass at the same time, the phase angles differ by 180°, or π radians, and the waves are said to be out of phase (by 180° in this case).

## What is meant by phase of SHM?

Phase simply means an angular term which represents situation of a particle in SHM at a certain instant. Let one SHM is x1=Asinωt and another SHM which is differ by first SHM of phase angle ϕ then other SHM is, x2=Asin(ωt+ϕ) Clear that phase of oscillation is state of oscillation of particle performing SHM.

## What is phase difference in SHM?

Solution : When SHM particle has maximum acceleration, its velocity is zero and acceleration is zero its velocity is maximum and hence phase difference `=(pi)/(2) = 0.5 pi`.

## What are units of phase?

Its unit is radians/meter, but we frequently convert it to degrees/meter. For a mathematical wave, the phase constant tells you how displaced a wave is from an equilibrium or zero position.

## What is phase and amplitude?

The Amplitude is the height from the center line to the peak (or to the trough). Or we can measure the height from highest to lowest points and divide that by 2. The Phase Shift is how far the function is shifted horizontally from the usual position.

## How do you find the phase?

1. Determine whether it’s a shifted sine or cosine.
2. Look at the graph to the right of the vertical axis.
3. Find the first:
4. Calculate the distance from the vertical line to that point.
5. If the function was a sine, subtract π/2 from that distance.

## What is phase angle formula?

You can determine the phase angle simply by looking at the time difference between the voltage and current waveforms. This is equal to the time difference between adjacent current and voltage peaks, divided by 180 degrees.

## What is the difference between angle and phase?

ANGLE command always give result in range [-pi, pi]. phase(X) command will give answer greater than pi for the second value (difference between phases values should be less than pi). At this time angle(X) command will give value near -pi for the second argument (wrap values into range [-pi, pi]).

## What is phase of a wave Class 12?

Phase of a wave describes the state of motion as the wave sweeps through an element at a particular position.

## What is phase of a particle?

phase is the relative position of the particle w.r.t the origin , Thus, it can also be used to find the direction of motion of the particle at a given time.

## What is phase give an example?

A simple description is that a phase is a region of material that is chemically uniform, physically distinct, and (often) mechanically separable. In a system consisting of ice and water in a glass jar, the ice cubes are one phase, the water is a second phase, and the humid air is a third phase over the ice and water.

## What is phase of a sine wave?

The phase of an oscillation or signal refers to a sinusoidal function such as the following: where , , and are constant parameters called the amplitude, frequency, and phase of the sinusoid. These signals are periodic with period , and they are identical except for a displacement of along the axis.

## What does phase mean in science?

phase, in thermodynamics, chemically and physically uniform or homogeneous quantity of matter that can be separated mechanically from a nonhomogeneous mixture and that may consist of a single substance or a mixture of substances.

## What is in phase and out of phase in physics?

Two sound waves of the same frequency that are perfectly aligned have a phase difference of 0 and are said to be “in phase.” Two waves that are in phase add to produce a sound wave with an amplitude equal to the sum of the amplitudes of the two waves.

## What is phase current?

Phase current is the current through any one component comprising a three-phase source or load. In balanced “Y” circuits, the line voltage is equal to phase voltage times the square root of 3, while the line current is equal to phase current.

## What is phase in a signal?

In electronic signaling, phase is a definition of the position of a point in time (instant) on a waveform cycle. A complete cycle is defined as 360 degrees of phase as shown in Illustration A below. Phase can also be an expression of relative displacement between or among waves having the same frequency .

## What is the phase of a function?

The phase function is a dimensionless and normalized version of the scattering function, such that the integral of the phase function over 4π steradians equals 4π. The phase function for a given wavelength is a property of the medium, not of the incident radiation, provided the incident radiation is unpolarized.

## What is phase physics Quora?

Phase is a particular point in time on the cycle of a waveform, measured as an angle in degrees. A complete cycle is 360°. The waves are in phase if the waves are either 0 or 360° apart. The resulting amplitude (sum of the waves) is twice the original.

## What are the phase of SHM Class 11?

The angle `(omegat+alpha)` is called the phase angle or simply the phase of SHM.
