Dual Nature of Radiation and Matter - Result Question 59

63. The X-rays cannot be diffracted by means of an ordinary grating because of

[1997]

(a) high speed

(b) short wavelength

(c) large wavelength

(d) none of these

Show Answer

Answer:

Correct Answer: 63. (b)

Solution:

  1. (b) We know that the $X$-rays are of short wavelength as compared to grating constant of optical grating. As a result of this, it makes difficult to observe $X$-rays diffraction with ordinary grating.
