TESTE DEIN WISSEN

Which of the following is the correct description of Amplitude?

Lösung anzeigen
TESTE DEIN WISSEN

Amplitude is the maximum magnitude of displacement from equilibrium. It is denoted with the letter A

TESTE DEIN WISSEN

The wave speed is also known as ________.

Lösung anzeigen
TESTE DEIN WISSEN

Speed of propagation.

Lösung ausblenden
TESTE DEIN WISSEN

The perpendicular displacement of the medium to the direction of travel of the wave is called a transverse wave.

Which of the following is the correct description of the period?

Lösung anzeigen
TESTE DEIN WISSEN

The period is the time to complete one cycle. It's denoted by the letter T

TESTE DEIN WISSEN

Which of the following is the correct description of frequency

Lösung anzeigen
TESTE DEIN WISSEN

The frequency f is the number of cycles in a unit of time. It's denoted by the letter f

Lösung ausblenden
TESTE DEIN WISSEN

In a repetitive, or periodic, motion. Each particle in the medium undergoes periodic motion as the wave propagates. This is called a _______ wave.

TESTE DEIN WISSEN

Periodic

TESTE DEIN WISSEN

If you double the wavelength of a wave on a particular string without changing the physical properties of the string, what happens to the wave speed v and the frequency f?

Lösung anzeigen
TESTE DEIN WISSEN

v is unchanged and f becomes one-half as great.

Lösung ausblenden
TESTE DEIN WISSEN

The product of a wave’s wavelength and frequency has the same value no matter what the frequency is. This product equals the wave speed.

TESTE DEIN WISSEN

True

Lösung ausblenden
TESTE DEIN WISSEN

Are waves on a string  transverse or longitudinal

Lösung anzeigen
TESTE DEIN WISSEN

Transverse

Lösung ausblenden
TESTE DEIN WISSEN

The displacement of the medium in the same direction of travel of the wave is called a longitudinal wave.


Lösung anzeigen
TESTE DEIN WISSEN

True

Lösung ausblenden
TESTE DEIN WISSEN

Is the Amplitude dependent or independent on the wavelength or frequency?

Lösung anzeigen
TESTE DEIN WISSEN

No, Amplitude is independent of wavelength or frequency. Changing the frequency or wavelength has no effect on the amplitude, and changing the wave amplitude by itself has no effect on the frequency or wavelength.

TESTE DEIN WISSEN

Wave motion vs. particle motion.

Are the motion of the transverse wave along the string and the motion of a particle of the string the same?

Lösung anzeigen
TESTE DEIN WISSEN

No, they are not the same. The wave moves with constant speed v along the length of the string, while the motion of the particle is simple harmonic and transverse (perpendicular) to the length of the string.
