Question

In the diffraction pattern due to a single slit of width 'd' with incident light of wavelength ${}^{\prime }{\lambda }^{\prime }$, at an angle of diffraction ${}^{\prime }{\theta }^{\prime }$, the condition for first minimum is

• A. $\lambda sin\theta =d$
• B. $dcos\theta =\lambda$
• C. $dsin\theta =\lambda$
• D. $\lambda cos\theta =d$

Answer 1

The correct option is C $dsin\theta =\lambda$

The correct option should be option c.
