What is the working principle of stroboscope?
What is the working principle of stroboscope?
A stroboscope or strobe is an instrument that works on the phenomenon of stroboscopic effect. It creates a stop motion effect of a rotating object by flashing a high-intensity light on it. This appearance of a moving object to be stationary can be used to study rotating, oscillating or vibrating objects.
What is stroboscope & how it is used?
The stroboscope is an intense, high speed light source used for visual analysis of objects in periodic motion and for high speed photography. Objects in rapid periodic motion can be studied by using the stroboscope to produce an optical illusion of stopped or slowed motion.
How a stroboscope is used for shaft speed measurement?
The speed is measured by adjusting the frequency so that the moving objects are visible only at specific intervals of time. A distinctive mark is made on the shaft or a disc is attached to a shaft whose speed is to be measured. A strobotron is used as source of light to flash light directly on the mark.
How a stroboscope is used to measure the speed of rotating disc?
Stroboscope was invented by “Simon von Stampfer”, stroboscope can be used to study the periodic motion or it can be used to determine the rotation speed by shining a bright light at intervals so that the moving or rotating object will appear stationary.
Which is true about stroboscope?
2. The strain energy of the equivalent system is equal to that of the original system….
Q. | Which of the following statements is true about stroboscope? |
---|---|
C. | Stroboscope uses electromagnetic radiations to measure frequency |
D. | All of the above |
Answer» a. Stroboscope is non-contact type frequency instrument |
What kind of instrument which is called a stroboscope?
A stroboscope, also known as a strobe, is an instrument used to make a cyclically moving object appear to be slow-moving, or stationary. It consists of either a rotating disk with slots or holes or a lamp such as a flashtube which produces brief repetitive flashes of light.
What are the advantages of stroboscope?
The principal advantage of the stroboscopic tachometer is that it permits the angular speeds of rotation of objects to be measured without contact between the instrument and the object. Consequently, speeds can be measured for objects that are visible but not easily accessible.
What are the practical applications of stroboscope?
Applications. Stroboscopes play an important role in the study of stresses on machinery in motion, and in many other forms of research. They are also used as measuring instruments for determining cyclic speed. As a timing light they are used to set the ignition timing of internal combustion engines.

Who invented stroboscope?
Simon von StampferStroboscope / Inventor
How does a stroboscope work?
The stroboscope is adjusted such that the light flashes directly on the reference marks. The frequency of these flashes is varied and adjusted by means of a frequency adjustment knob until the reference marks on the disc appear to be stationary.
How do you study a moving object with a stroboscope?
Objects in rapid periodic motion can be studied by using the stroboscope to produce an optical illusion of stopped or slowed motion. When the flash repetition rate of the stroboscope is exactly the same as the object movement frequency, or an integral submultiple thereof, the moving object will appear to be stationary.
Why do the flashing lights on the stroboscope appear stationary?
When the frequency of the flashing lights from the stroboscope is adjusted to synchronize with the fan rotating speed, the number of apparently stationary fan blades you see corresponds to the actual number of fan blades.* 2.
What is a stroboscope tachometer?
A stroboscope or stroboscopic tachometer is also called a flashlight stroboscope used for the measurement of angular velocity or rotational speed by the stroboscopic method. It consists of a flashing light of variable frequency in which the flashing frequency of the stroboscope light can be adjusted.
