Name: 19. If a wave has a peak amplitude of 17 cm, what is its RMS amplitude? NOTE: please calculate your answer in cm, not meters. 20. If a wave has an RMS amplitude of 240 mm, what is its peak ampli

Answer :

The peak amplitude of the wave is approximately 339 mm.

19. If a wave has a peak amplitude of 17 cm, the RMS (Root Mean Square) amplitude can be calculated by dividing the peak amplitude by the square root of 2:

RMS amplitude = Peak amplitude / √2 = 17 cm / √2 ≈ 12 cm.

Therefore, the RMS amplitude of the wave is approximately 12 cm.

20. If a wave has an RMS amplitude of 240 mm, the peak amplitude can be calculated by multiplying the RMS amplitude by the square root of 2:

Peak amplitude = RMS amplitude * √2 = 240 mm * √2 ≈ 339 mm.

19. RMS (Root Mean Square) amplitude is a measure of the average amplitude of a wave. It is calculated by taking the square root of the average of the squares of the instantaneous amplitudes over a period of time.

In this case, if the wave has a peak amplitude of 17 cm, the RMS amplitude can be calculated by dividing the peak amplitude by the square root of 2 (√2). The factor of √2 is used because the RMS amplitude represents the equivalent steady or constant value of the wave.

20. The RMS (Root Mean Square) amplitude of a wave is a measure of the average amplitude over a period of time. It is often used to quantify the strength or intensity of a wave.

In this case, if the wave has an RMS amplitude of 240 mm, we can calculate the peak amplitude by multiplying the RMS amplitude by the square root of 2 (√2). The factor of √2 is used because the peak amplitude represents the maximum value reached by the wave.

By applying these calculations, we can determine the RMS and peak amplitudes of the given waves.
