1.	Assertion: To observe diffraction of light the size of obstacle/aperture should be of the order of `10^-7m`. Reason: `10^-7m` is the order of wavelength of visible light.A. (a) If both assertion and reason are true and reason is the correct explanation of assertion.B. (b) If both assertion and reason are true but reason is not the correct explanation of assertion.C. (c) If assertion is true but reason is false.D. (d) If assertion and reason both are false.
Answer» Correct Answer - A For diffraction to occur, the size of an obstacle/ aperture is comparable to the wavelength of light wave. The order of wavelength of light wave is `10^-7m` so diffraction occurs.
