Solution

The correct options are
C Both obeys laws of reflection
D Both are forms of energy
Sound waves and light waves are very different in nature. Both of them are waves and obey the characteristics of waves. So, both of them are forms of energy and follow laws of reflection.

Sound waves are mechanical waves and require a medium to propagate. Light waves, on the other hand are non-mechanical waves and do not require a medium for propagation. Light waves are always transverse whereas sound waves can be either transverse or longitudinal depending on the medium.
