Why Wolves Don't Chirp

The video explores how different animals use sound for communication, focusing on the differences between high and low frequency sounds. It explains that while both wolf howls and frog chirps are similar in volume, their frequencies affect how far they travel. Low frequency sounds, like those of wolves and elephants, travel farther and are used for long-distance communication. High frequency sounds, used by bats and dolphins, are better for echolocation as they reflect off obstacles. The video highlights the importance of frequency in determining the effectiveness of animal communication.

What determines the pitch of a sound?

• The type of animal making the sound

• The distance the sound travels

• The frequency of the sound waves

• The volume of the sound

Why do high-frequency sounds not travel as far as low-frequency sounds?

• They are less likely to reflect off obstacles

• They are louder

• They release more energy as heat

• They are absorbed by the air

How do low-frequency waves interact with obstacles?

• They reflect off obstacles

• They are absorbed by obstacles

• They bend around obstacles

• They pass through obstacles

Which animals are known to use low-frequency sounds for long-distance communication?

• Bats and dolphins

• Wolves and elephants

• Tree frogs and birds

• Cats and dogs

Why do bats and dolphins use high-frequency sounds?

• To communicate over long distances

• To avoid obstacles

• To reflect off small objects

• To conserve energy
