Which light wave will spread out more after passing through a narrow rectangular opening?

Question

Quizplus · Accepted Answer

The phenomenon of Diffraction occurs when a wave passes through an opening (in this case, a narrow rectangular opening). The diffraction pattern that is generated by the wave depends on its wavelength. The longer the wavelength, the more the wave bends or diffracts around the edges of the opening. Therefore, a wave with a greater wavelength will spread out more after passing through the opening. Additionally, intensity does not affect diffraction. Therefore, the answer is option C as it satisfies the criteria of having a greater wavelength with a greater intensity.
