Amplitud

The video tutorial explains the concept of wave amplitude, highlighting its graphical representation as the distance between the crest and the midpoint of a wave. It further discusses the relationship between amplitude and wave energy, using sound waves as an example to illustrate how higher amplitude results in louder sounds.

What does the amplitude of a wave represent in its graphical depiction?

• The distance from crest to midpoint

• The frequency of the wave

• The wavelength of the wave

• The speed of the wave

What is the midpoint in the context of wave amplitude?

• The average position of the wave

• The lowest point of the wave

• The highest point of the wave

• The point where the wave starts

How is wave energy related to amplitude?

• Amplitude is inversely proportional to energy

• Higher amplitude means higher energy

• Amplitude does not affect energy

• Higher amplitude means lower energy

In the context of sound waves, what effect does a higher amplitude have?

• It makes the sound softer

• It decreases the sound's frequency

• It makes the sound louder

• It changes the pitch of the sound

Which of the following is true about the relationship between amplitude and sound?

• Amplitude affects the loudness of sound

• Amplitude affects the pitch of sound

• Amplitude affects the speed of sound

• Amplitude affects the direction of sound
