# Young's Two-Slit Exp: Calculate OP w/ Wavelength 6.0*10^-7 m

• therisingpower
In summary, in a Young's two slit experiment, two coherent sources of light, S1 and S2, are separated by a distance of 0.50mm. Point O is equidistant from S1 and S2 and is located on screen A, which is 0.80m away from the slits. When a thin parallel-sided piece of glass G with a thickness of 3.6*10^-6 m is placed near S1, the center of the fringe system moves from O to a point P. Using a wavelength of 6.0*10^-7 m for the monochromatic light and a refractive index of 1.5 for the glass, the distance OP can be calculated.

S1 and S2 are two coherent sources of light in a Young's two slit experiment separated by a distance 0.50mm, and O is a point equidistant from S1 and S2. O is on screen A which is 0.80m from the slits.

When a thin parallel-sided piece of glass G of thickness 3.6*10^-6 m is placed near S1, the centre of the fringe system moves from O to a point P. Calculate OP if the wavelength of the monochromatic light from the two slits is 6.0*10^-7 m and the refractive index of the glass is 1.5.

## 1. What is Young's Two-Slit Experiment?

Young's Two-Slit Experiment is an experiment that demonstrates the wave nature of light. It involves shining a beam of light through two narrow slits and observing the interference pattern that is formed on a screen behind the slits.

## 2. How do you calculate OP in Young's Two-Slit Experiment?

In Young's Two-Slit Experiment, OP (path difference) is calculated by taking the distance between the two slits and multiplying it by the sine of the angle between the screen and the center line drawn between the two slits. This can be represented by the equation OP = d * sin(theta), where d is the distance between the slits and theta is the angle.

## 3. What is the significance of wavelength in Young's Two-Slit Experiment?

The wavelength of light is a crucial factor in Young's Two-Slit Experiment as it determines the spacing between the bright and dark fringes in the interference pattern. A shorter wavelength will result in a smaller spacing and a longer wavelength will result in a larger spacing between the fringes.

## 4. What is the wavelength used in the calculation of OP in this experiment?

The wavelength used in the calculation of OP in this experiment is 6.0 x 10^-7 meters.

## 5. How can the results of Young's Two-Slit Experiment be used to prove the wave nature of light?

The interference pattern observed in Young's Two-Slit Experiment is a result of the superposition of light waves, which is a characteristic of wave behavior. This provides evidence for the wave nature of light and supports the theory that light can behave as both a wave and a particle.
