to measure wavelength and other wave characters
He is the inventorof the Michelson interferometer.
The Michelson Interferometer is used to create an interference pattern by splitting a beam of light into two paths. This device has several important scientific applications for experimentation.
a compensating plate is used in michelson interferometer to compensate the additional path difference of ray 1
The fringe pattern observed in a Michelson interferometer is significant because it provides information about the interference of light waves, which can be used to measure small distances, test optical components, and study the properties of light.
Michelson's interferometer is used in interferometry to make precise measurements of distance, wavelength, and index of refraction. It is also used in the field of spectroscopy to analyze the interference patterns of light to determine the properties of materials. Additionally, it is used in the detection of gravitational waves.
The Michelson device operates on Light waves. It is not a sound apparatus. One cannot use a telescope to analyze sounds, right?
Circular fringes are obtained in a Michelson interferometer due to the spherical wavefronts produced by the point light source. The light waves that interfere come from a point source, creating a series of concentric circles of constructive and destructive interference known as circular fringes. This phenomenon occurs as the waves reflect off the two mirrors in the interferometer and interfere with each other.
An example of an interferometer is the Michelson interferometer, which is commonly used in the field of optics to measure the wavelength of light, test optical components, and determine refractive indices of materials. It works by splitting a light beam into two paths, recombining them, and measuring interference patterns to extract information about the light.
In michelson interferometer experiment, when we see the fringe pattern ,it depends on the angle in which our eye see it. This is due to the angle theta between the eye and and fringe pattern. The second reason is the factor d, the distance between the mirrors M1 amd M2.
The interferometer was first discovered by Albert A. Michelson in the late 19th century. He used it to conduct experiments to detect the effect of Earth's motion on the speed of light. The Michelson interferometer has since become a widely used tool in physics for measuring small displacements, refractive index changes, and interference phenomena.
In michelson interferometer the mirros are perpendicular and because of our eye viewed direction and angle theta the fringes are circular
initially the two beams i.e. one reflected and one transmitted from semi reflecting glass were in different phase but when they superimpose two interference take place - constructive and destructive. since in both the interferences amplitude changes.
