Answer 2

(a) 50,000 Hz

Explanation:

Humans are capable of hearing sound waves of frequency between 20 Hz and 20,000 Hz only. This is called the Sonic waves. The audio freqency is called audible frequency. The sound above this range is called ultra sonic. Humans are not capable of hearing both the sub sonic and ultra sonic frequencies.

Dogs can hear frequencies that are beyond what humans can hear. The frequencies that dogs can hear are called ultrasonic frequencies. Dogs typically can detect sounds up to 50,000 Hz. In the upper frequencies of a dog's hearing range, the sounds can cause a dog irritation and discomfort.
