Amplitude of Sin Quiz

What is the definition of amplitude?

• The speed at which a vibrating body or wave moves through space.

• The maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position.

• The time it takes for a vibrating body or wave to complete one full cycle.

• The frequency of a vibrating body or wave.

How can you measure the amplitude on a graph?

• By measuring the horizontal distance between the highest point and the lowest point of the graph.

• By measuring the vertical distance between the highest point and the lowest point of the graph.

• By counting the number of peaks on the graph.

• By calculating the average of all the points on the graph.

Which equation can be used to calculate the amplitude of a wave?

• A = (Vmax + Vmin)

• A = (Vmax / Vmin)

• A = (Vmax * Vmin)

• A = (1/2) (Vmax - Vmin)

What does the amplitude of a wave represent?

• Maximum displacement or distance from the equilibrium position

• Wavelength of the wave

• Speed of the wave

• Frequency of the wave

If a wave has a high amplitude, what can you infer about the energy it carries?

• It carries more energy than a wave with low amplitude.

• It carries less energy than a wave with low amplitude.

• It carries the same amount of energy as a wave with low amplitude.

• The energy it carries is unrelated to its amplitude.

Which of the following waves has the highest amplitude?

• Option D

• Option B

• Option A

• Option C

If the amplitude of a wave is doubled, what happens to its energy?

• The energy of the wave is quadrupled.

• The energy of the wave is doubled.

• The energy of the wave is halved.

• The energy of the wave remains the same.
