(i) The property of sound similar to light is that in both reflection takes place. (ii) Sound can travel around comers but light cannot. Some people suffer from hearing impairment because their ear drum is damaged or absent. This can be from birth or may occur later on. Such people communicate with “sign language”. They can also use “hearing aids”.
