The video tutorial explains how to graph waves using X and Y axes, illustrating the sound patterns of crickets and frogs. It introduces the concept of amplitude, which measures the energy carried by a wave, and compares the amplitudes of sounds made by crickets and frogs, highlighting that louder sounds have higher amplitudes.

What does the horizontal line on a graph represent?

• Y axis

• Amplitude

• Z axis

• X axis

What is the term for the distance from the X axis to the top of a wave?

• Velocity

• Wavelength

• Amplitude

• Frequency

How do crickets produce their rhythmic sound?

• By rubbing their wings

• By croaking

• By rubbing their legs together

• By chirping

Which animal's sound is associated with a higher amplitude?

• Crickets

• Peepers

• Birds

• Cicadas

What does a higher amplitude indicate about a sound?

• It is softer

• It is louder

• It is slower

• It is faster
