What are Lissajous figures in physics?

Lissajous figure, also called Bowditch Curve, pattern produced by the intersection of two sinusoidal curves the axes of which are at right angles to each other. Lissajous used a narrow stream of sand pouring from the base of a compound pendulum to produce the curves.

What are Lissajous figures give examples?

For a ratio of 1, the figure is an ellipse, with special cases including circles (A = B, δ = π2 radians) and lines (δ = 0). Another simple Lissajous figure is the parabola ( ba = 2, δ = π4).

What is lissajous method explain it?

The Lissajous pattern indicates the phase difference by the shape of the X-Y plot. A straight line indicates a 0º or 180º phase difference. The angle of the line depends on the difference in amplitude between the two signals, a line at 45º to the horizontal means the amplitudes are equal.

What is Lissajous figure Mcq?

A Lissajous figure is a pattern which is displayed on the screen when sinusoidal signals are applied to both horizontal & vertical deflection plates of CRO. These are used to measure the frequency of the given signals and phase difference between the signals.

How do you draw a Lissajous figure?

What is the use of Lissajous pattern?

Why are Lissajous figures important?

The Lissajous figure is of high importance in physics in order to study the sinusoidal waves. The Lissajous figures are mainly used in analogue electronics to analyse the intersection of two or more sinusoidal wave constructing loops which is also known as knots in general.

How do you make a Lissajous figure?

What is heart of CRO?

CRT is the heart of CRO. Explanation: CRT stands for Cathode Ray Tube. It generates electron beam, accelerates and deflects the beam. It thus forms the heart of the CRO.

Where are oscilloscopes used?

Oscilloscopes are used in the sciences, medicine, engineering, automotive and the telecommunications industry. General-purpose instruments are used for maintenance of electronic equipment and laboratory work.

Where do Lissajous figure appear?

A Lissajous figure is displayed on the screen when sinusoidal signals are applied to both horizontal & vertical deflection plates of CRO. Hence, apply the sinusoidal signals, which have same amplitude and frequency to both horizontal and vertical deflection plates of CRO.

Is a circle a Lissajous figure?

Common Lissajous Curves (See more on the Ellipse.) In the example in Curvilinear Motion, the Lissajous figure is a circle. If A = B and a = b = 1, we will get a circle.

What is Lissajous figure in physics?

Definition of Lissajous figure. : any of an infinite variety of curves formed by combining two mutually perpendicular simple harmonic motions, commonly exhibited by the oscilloscope, and used in studying frequency, amplitude, and phase relations of harmonic variables.

What is the lissajou pattern?

The lissajou figure or the lissajou pattern is constructed by the intersection of two sinusoidal curved axes of which are perpendicular to each other or maintained at right angles to each other. The lissajou figure was initially studied by the American mathematician Nathaniel Bowditch in the year 1815.

What is a Lissajous curve?

Lis·​sa·​jous figure | \\ ¦lēsə¦zhü-\\. variants: or less commonly Lissajous curve. : any of an infinite variety of curves formed by combining two mutually perpendicular simple harmonic motions, commonly exhibited by the oscilloscope, and used in studying frequency, amplitude, and phase relations of harmonic variables.

What are Lissajous figures in movies?

Lissajous figures were sometimes displayed on oscilloscopes meant to simulate high-tech equipment in science-fiction TV shows and movies in the 1960s and 1970s. The title sequence by John Whitney for Alfred Hitchcock ‘s 1958 feature film Vertigo is based on Lissajous figures.
