Circle and correct the statements below that are false about diffraction. Justify your corrections. (a)  Diffraction of light is evidence that we can treat light as a particle. (b)  For single slit diffraction, constructive interference of light will present as dark spots on screen. (c)  For single slit diffraction, as the wavelength of the light decreases, the diffraction pattern shrinks with all fringes getting narrower. (d)  When λ/w is large in this scenario [λ >> w], there are little to no effects of diffraction observed. (e)  All of the above statements are true.

Interference of Light

The word "constructive" signifies addition in interference. Constructive interference occurs when the path of the waves that start from the slit differs by 1 entire wavelength or in the intervals of the same. Hence, the waves that are presented on the screen are in phase (crest to crest/trough to trough). The waves interfering constructively forms bright fringes on the screen.
