What happens to the pattern if we try to determine which slit the electron goes through by using a laser placed directly behind the slits?

What happens to the pattern if we try to determine which slit the electron goes through by using a laser placed directly behind the slits?

What happens to the pattern if we try to determine which slit the electron goes through by using a laser placed directly behind the slits? If the rate of electrons going through the slits is decreased to one electron per hour, the same interference pattern is observed.

What is the relation between path difference and intensity?

The path difference between the two waves is given to be 18th of the wavelength of the interfering waves. It can be written as, Δx=λ8, where λ is the wavelength of the interfering waves. Hence, the ratio of intensity is 0.85.

How is YDSE intensity calculated?

Let’s calculate the expression for the intensity of interfering waves due to coherent sources. The expression turns out to be I =4 Io cos^2 (phi/2). Created by Mahesh Shenoy.

What is the formula of maximum intensity?

Hint: To find the ratio of maximum and minimum intensity due to superposition of two waves can be given by ratio of addition and subtraction of amplitudes, which can be given mathematically as, ImaxImin=(a+b)2(a−b)2, form these we will find the values of amplitudes and from that we will find the ratio of intensities by …

Is Intensity same in YDSE?

The phase difference for the central bright fringe is zero i.e φ=0. Therefore, the intensity of each slit on the central bright fringe is I1=I04. Hence option (D) is the correct one.

Does intensity affect fringe spacing?

When the intensity of ONE of the fringes is reduced, the amplitude of ONE of the fringes is also reduced (I = A²) .

How does the double slit experiment prove the wave theory of light?

In quantum mechanics the double-slit experiment demonstrated the inseparability of the wave and particle natures of light and other quantum particles. If classical particles are fired in a straight line through a slit they will all strike the screen in a pattern the same size and shape as the slit.
