Why does sound wave bend around obstacle more than light waves​

Since the wavelength of visible light is on the order of 0.5 microns, or 0.0005 mm, light will only diffract when going through very narrow openings. Sound waves, on the other hand, have a wavelength on the order of 1 meter and diffract very easily. This allows sound waves to bend around corners.

t.                 w               e                 n                   t                 y                 c             h               a           r           a               c                 t             e             r             s        

layer a is the exosphere and layer b is the thermosphere.   is the answer i think but i hope this .
