Question
In the Fraunhofer diffraction pattern of a double slit, it is found that the fourth secondary maximum is missing. What is the ratio of slit width $b$ to slit separation $h$ ?
Instant Answer
Step 1
The secondary maxima are the bright fringes that occur between the primary maxima. The problem states that the fourth secondary maximum is missing, and we need to find the ratio of the slit width (b) to the slit separation (h). Show more…

A double slit produces a diffraction pattern that is a combination of single and double slit interference. Find the ratio of the width of the slits (D) to the separation between them (d), if the third minimum of the single slit pattern falls on the fourth-order maximum of the double slit pattern. (This will greatly reduce the intensity of the fourth-order maximum. Assume the central maxima of the single slit and double slit interference patterns are located at the same place on the screen.)
A double slit produces a diffraction pattern that is a combination of single and double slit interference. Find the ratio of the width of the slits to the separation between them, if the first minimum of the single slit pattern falls on the fifth maximum of the double slit pattern. (This will greatly reduce the intensity of the fifth maximum.)
If, in a two-slit interference pattern, there are 8 bright fringes within the first side peak of the diffraction envelope and diffraction minima coincide with two-slit interference maxima, then what is the ratio of slit separation to slit width?
