For diffraction to occur, the size of an obstacle/aperture is comparable to the Wavelength of light wave.

Q. 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.

If the Assertion and Reason are true but Reason is not correct explanation of Assertion

If Assertion is true but, Reason is false

If Assertion is false but, Reason is true

For diffraction to occur, the size of an obstacle/aperture is comparable to the Wavelength of light wave.

Q. Assertion : To observe diffraction of light the size of obstacle/aperture should be of the order of $1 0^{- 7} m$ .
Reason : $1 0^{- 7} m$ is the order of wavelength of visible light.
