In Davisson and Germer experiment if of diffraction is `50^@`, find the glancing

In Davisson and Germer experiment states the observations which led to show the wave nature of electrons?

Mention the significance of Davisson and Germer's experiment. An alpha-particl e and a proton are accelerated from rest through the same potential difference V. find the ratio of de-Broglie wavelength associated with them.

With what purpose was famous Davisson Germer experiment with electrons performed?

In Young's double slit experiment, the widths of two slits are in the ratio 1:4 . Find at the ratio of maximum and minimum intensity in the interfernce pattern obtained.

In Young's double slit experiment, the widths of two slits are in the ratio 1:4 . Find at the ratio of maximum and minimum intensity in the interfernce pattern obtained.

If the two slits in Young's experiment have widths in the ratio 4:9 ,then find the ratio of intesnity at the maxmum to the intesity at the minimum in the interference pattern.
