Using X-rays of wavelength 141 pm, the angle of incidence for maximum intensity first order reflection for four different crystals are given. Which crystal has larger interplanar distance ?

A

`20.0^(@)`

B

`27.4^(@)`

C

`35.8^(@)`

D

`50^(@)`

Text Solution

Verified by Experts

The correct Answer is:
A
From Bragg.s equation, `nlamda=2dsintheta`
Then, `(nlamda)/(2)=d sin theta`
`(nlamda)/(2)=dsintheta`.
`(nlamda)/(2)` is constant hence when `sin theta` is minimum d is maximum.
