State whether the following statements are correct or incorrect and explain. 

Diffraction, Wavelength and Slit Width Diffraction Occurs For All Waves Diffraction only occurs for Electromagnetic Waves The longer the wavelength the more rapidly waves spread out The narrower the slit or opening the more rapidly the wave spreads out The wider the slit or opening the more rapidly the wave spreads out Diffraction only occurs for Mechanical Waves The shorter the wavelength the faster the wave spreads out The greater the amplitude of the wave the faster it spreads out.
