Question

Bragg's equation will have no solution if

Answer 1

if angle is zero between light ray and surface

Answer 2

Answer: The angle between the incident ray and surface of the crystal is 0.

Explanation:

Bragg's equation tells us about the direct relationship between the wavelength of lines and the distance between the crystal planes. The equation used given by Bragg is:

$n\lambda =2d\sin\theta$

where,

n = integer (n = 1,2,3....)

$\lambda$ = Wavelength of the ray

d = distance between the two crystal planes

$\theta$ = angle between the incident ray and the surface of the crystal

This equation will have no solution when $\theta=0$ which means that $\sin\theta=0$

Hence, Bragg's equation will have no solution when $\theta=0$
