What is a nonexample of amplitude? - Answers Well, friend, a nonexample of amplitude could be the color of a painting or the type of brush used Amplitude is all about the distance from the midpoint to the peak of a wave, so things like
What is high and low amplitude? - Answers In all cases, the amplitude is a measure of the "power" or the "energy" in that motion or wave As regards high amplitude and low amplitude, this is a designation as the the "amount" of energy in a
Why does a wave with a large amplitude carry more energy than . . . - Answers A wave with high amplitude? A wave with high amplitude has large peaks and troughs, indicating a significant amount of energy This type of wave carries more energy than a wave with small
What happens when you decrease amplitude Of a wave? When the amplitude of a wave is decreased, the wave becomes less intense and has lower energy This means that the wave will appear smaller in magnitude and may have a quieter or weaker effect on
What happens to the volume of sound when the amplitude increases . . . When the amplitude of a sound wave increases, the volume or loudness of the sound also increases This is because amplitude is directly related to the amount of energy in a sound wave, and a
What are examples of low amplitude sounds? - Answers Low amplitude examples include a gentle breeze brushing against your face, the soft rustle of leaves in a tree, and the faint ticking of a clock in the distance These are subtle and quiet sounds
Does the pitch of the sound depend on the amplitude? - Answers The amplitude of a sound is the sound energy or "loudness" of the sound The higher the amplitude of the sound wave, the more energy in the wave and the louder it is source, medium and sender
Which carries more energy a wave with large amplitude or small . . . A wave with high amplitude? A wave with high amplitude has large peaks and troughs, indicating a significant amount of energy This type of wave carries more energy than a wave with small
What happens when you change the amplitude? - Answers For sound and similar waves we say a change of amplitude changes the intensity of the wave More complex Cases:The basic characteristics of a simple harmonic wave are the amplitude, frequency and
What is the relationship between amplitude and wavelength in . . . - Answers The amplitude of a wave does not affect its wavelength as wavelength is determined by the speed of the wave and its frequency Frequency and wavelength are inversely proportional; as frequency
