is amplitude the same as magnitude?

Amplitude is the difference between highest and lowest point of a wave. Magnitude is the result of measurement or compare. ... The amplitude of a sine wave is the maximum value the sine wave gets, in either the positive or negative direction. While magnitude is the value the sine wave has at a certain point on time.

The amplitude of a sinusoidal function is one-half of the positive difference between the maximum and minimum values of a function. It is simply the vertical distance from the x-axis (or midline) to the highest (or lowest) point on the curve.

No. The RMS represents the amount of energy in the signal. This is the same regardless of the polarity of voltage or current. You can prove this to yourself by going through the RMS calculation.

In particular, the wave Asin(x) has amplitude A because its extreme points are at ±A and its equilibrium would like at 0. The "range" (or "peak-to-peak amplitude") sometimes refers to the difference of largest and smallest values in a wave - so 2A for sin(x).

For any wave, the amplitude can be anything. There is a simple relationship between wavelength, frequency, and velocity. You can see this easily: a wave travels one wavelength L in one period P, so v = L/P. The period P is defined as the inverse of the frequency f, so P = 1/f.

What is the relation between the amplitude and the frequency of a wave? The amplitude and the frequency of a wave are independent of each other. The amplitude and the frequency of a wave are equal. The amplitude decreases with an increase in the frequency of a wave.

Scalar quantities have only magnitude; vector quantities have both magnitude and direction. ... It has only magnitude, no direction. Force, displacement, and acceleration all occur with a designated direction.

The lower the power, or amplitude, the lower the wave form peeks all while frequency, cycle and wavelength remain the same. Example 5 - Amplitude shown by the hight or peeks of the wave form. Phase is the same frequency, same cycle, same wavelength, but are 2 or more wave forms not exactly aligned together.

Magnitude is expressed in whole numbers and decimal fractions. For example, a magnitude 5.3 is a moderate earthquake, and a 6.3 is a strong earthquake. Because of the logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude as measured on a seismogram.

Lesson Summary The frequency is just the opposite; it's the number of wave cycles that are completed in one second. Amplitude and wavelength are both measures of distance. The amplitude measures the height of the crest of the wave from the midline. The wavelength measures the horizontal distance between cycles.

Volume (amplitude ) – shown by the height of the waves displayed. The larger the amplitude of the waves, the louder the sound. Pitch (frequency) – shown by the spacing of the waves displayed. The closer together the waves are, the higher the pitch of the sound.

['Amplitude refers to the height of the signal; it is measured in volts, amperes or watts.', 'Period refers to the amount of time in which a signal completes one cycle; it is measured in seconds.']

The apparent magnitude is the observed visible brightness from Earth which depends on the distance of the object. The absolute magnitude is the apparent magnitude at a distance of 10 pc (3.1×1017 m), therefore the bolometric absolute magnitude is a logarithmic measure of the bolometric luminosity.

AMPLITUDE AND WAVELENGTH The amplitude of a wave is the height of a wave as measured from the highest point on the wave (peak or crest) to the lowest point on the wave (trough). Wavelength refers to the length of a wave from one peak to the next. ... Wavelength is directly related to the frequency of a given wave form.

Absolute magnitude. ... An object's absolute magnitude is defined to be equal to the apparent magnitude that the object would have if it were viewed from a distance of exactly 10 parsecs (32.6 light-years), without extinction (or dimming) of its light due to absorption by interstellar matter and cosmic dust.

The magnitude scale is logarithmic. That just means that if you add 1 to an earthquake's magnitude, you multiply the shaking by 10. ... For example, if the magnitude of one quake is 6 and another is 4, than the difference in magnitudes is 2, so the stronger earthquake shakes 10^2 or 100 times as hard as the milder one.
