The distance between planes of ions parallel of the unit cell of sodium chloride is 282 pm. The smallest angle of reflection observed in the X-ray diffraction pattern is `5.97^(@)` . Calculate the wavelength of the incident radiation.

Text Solution

Verified by Experts

`n lambda = 2 d sin theta`
`rArr 1xx lambda = 2xx282xx10^(-12)sin 5.97`
`therefore lambda = 5.86xx10^(-11)m=58.6` pm
