If one of the slit is covered, what would take place in the intensity of the position of central maxima?

In the diffraction of a single slit experiment, how would the width of and the intensity of central maximum change,if slit width is halved and

In the diffraction of a single slit experiment, how would the width of and the intensity of central maximum change,if visible light of longer wavelength is used?

In the Young.s double slit experiment , two slits 0.125mm apart are illuminated by light of wavelength 4500@A . The screen is 1 m away from the plane of the slits. Find the separation between second bright fringes on both sides of central maxima.

What change is observed in interference pattern of Young's double slit experiment ,if one of the two slits is painted,so that it transmits half the light intensity of the other?

Two nearby narrow slits are illuminated by a single monochromatic source. Name the pattern obtained on the screen. One of the slits is now covered. What is the name of the pattern now obtained on the screen? Write two differences between the pattens obtained in the two cases.

A lens having focal length f and aperture of diameter d//2 in the central region of the lens is covered by a black paper.Focal length of the lens and intensity of image image now will be respectively

Figure EP 10.19 shows a two slit arrangement with a source which emits unpolarised light. P is a polariser with axis whose direction is not given. If I_0 is the intenstiy of the principal maxima when no polariser is present, calculate in the present case, the intensity of the principal maxima as well as of the first minima.

Two slits 0.125 mm aprt are illuinated by igth of wavelength 4500 ^@A .The screen is one metre way from the plane of the slits.Find the separation between the second bright fringes on both sides of the central maximum.

Answer the following questions: In a single slit diffraction experiment, the width of the slit is made double the original width. How does this affect the size and intensity of the central diffraction band?

Diffraction of light Diffraction of light is the phenomenon of bending of light round corners of an obstacle or aperture and spreading into the geometraicl shadow of the diffracting object. The condition for diffractio of light is the size of the aperature should be comparable to the wavelength of incident light. so in daily life, we find that diffraction of sound is more common than the diffraction of light. width of central maxima is {formula= ((2lambdaD)/d) } In single slit diffraction experiment, if the width of the slit is doubled, if the intensity of central fringe diffraction band becomes.
