Yellow light is used in a single slit diffraction experiment with a slit width of $0.6 \, mm$. If the yellow light is replaced by $X$-rays,then the pattern will reveal:

Angular width $(\beta)$ of the central maximum of a diffraction pattern on a single slit does not depend upon

The phenomenon that explains why light waves do not travel in a straight line is known as .......

Two slits are $1 \,mm$ apart and the screen is located $1 \,m$ away from the slits. $A$ light of wavelength $500 \,nm$ is used. The width of each slit to obtain $10$ maxima of the double slit pattern within the central maximum of the single slit pattern is $\ldots \ldots \ldots \times 10^{-4} \,m$.

At the first minimum adjacent to the central maximum of a single-slit diffraction pattern,the phase difference between the Huygens' wavelet from the edge of the slit and the wavelet from the midpoint of the slit is

In a single slit diffraction pattern,the distance between the plane of the slit and the screen is $1.3 \ m$. The width of the slit is $0.65 \ mm$ and the second maximum is formed at a distance of $2.6 \ mm$ from the center of the screen. The wavelength of light used is: (in $Å$)
