In the equation sin(θ)=aλ for single-slit diffraction, θ is:
Correct answer: B. the angle to the first minimum
- A. the angle to the second maximum
- B. the angle to the first minimum
- C. the phase angle between the extreme rays
- D. N⋅π where N is an integer
Explanation
In the equation for single-slit diffraction, sin(θ)=aλ , θ represents the angle to the first minimum (first dark fringe). This angle is measured from the central maximum.Incorrect Options:

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
