- What is the interference of light? Write two essential . . . - Toppr
(i) $$\beta \propto D$$, therefore with the decrease of separation between the plane of slits and screen, the fringe width decreases (ii) On increasing the separation between two slits (d), the fringe separation decreases as $$\beta$$ is inversely proportional to d (i e $$\beta \propto \frac{1}{d}$$ )
- In a double-slit arrangement the slits are separated by a . . . - Toppr
If the distance between the first maxima and the fifth minima of a double-slit pattern is $$7mm$$ and the slits are separated by $$0 15mm$$ with the screen $$50cm$$ from the slits, then wavelength of the light used is
- Suppose that Youngs experiment is performed with blue-green . . . - Toppr
In a Youngs interference experiment, the two slits are separated by 0 150 mm and the incident light includes two wavelengths: $$\lambda_1 = 540$$ nm (green) and $$\lambda_2 = 450$$ nm (blue) The overlapping interference patterns are observed on a screen 1 40 m from the slits Calculate the minimum distance from the center of the screen to a
- In the figure, a parallel beam of white light is incident on . . . - Toppr
White light is used to illuminate the two slits in a Young's double slit experiment The separation between the slits is d and the screen is at a distance D (> > d) from the slits At a point on the screen directly in front of one of the slits, certain wavelengths are missing Some of these missing wavelengths are :
- In a Youngs double slit experiment, light has a frequency of
In Young's double slit experiment, using monochromatic light, fringes are obtained on a screen placed at some distance from the slits If the screen is moved by 5 × 10 − 2 m towards the slits, the change in the fringe width is 3 × 10 − 5 m If the distance between the two slits is 10 − 3 m, calculate wavelength of the light used
- At a point on the in YDSE, 3^{text {rd }} maxima is observed t . . . - Toppr
In a Young's doubleslit experiment, first maxima is observed at a fixed point P on the screen Now, the screen is continuously moved away from the plane of slits The ratio of intensity at point P to the intensity at point O (centre of the screen)
- In a YDSE light of two different wavelengths (^, 12) are . . . - Toppr
In a Young's double slits experiment light consisting of two wavelengths λ 1 = 500 n m and λ 2 = 700 n m is incident normally on the slits If the distance from the central maxima where the maximas due to wavelengths coincide for the first time after central maxima
- produced UI Draw a graph shou experiment when ph showing the . . . - Toppr
Draw a graph showing the variation of intensity versus the position on the screen in Youngs experiment when (a) both the slits are opened and (b) one of the slits is closed What is the effect on the interference pattern in Youngs double slit experiment when: (i) Screen is moved closer to the plane of slits?
