Question

Hertz is the SI unit of ___________.
1. Frequency
2. Wavelength
3. Amplitude
4. Force

Answer 1

Correct Answer - Option 1 : Frequency

The correct answer is Frequency

• Frequency
  • It tells us how frequently an event occurs.
  • The number of complete waves produced in one second is called the frequency of the waves.
  • Hertz is the SI unit of Frequency. It is named in the honor of Rudolf Hertz.
  • 1 Hertz= 1 vibration per second.

• Wavelength
  • Wavelength is the minimum distance covered by a wave after which a sound wave repeats itself.
  • Its SI unit is meter.
• Amplitude
  • The amplitude of a sound wave is the measure of the height of the wave.
  • The amplitude of the sound is directly proportional to the Loudness.
  • The amplitude is small, then the sound will be feeble.
• Force
  • Any action which causes pull or push on a body is called force.
  • It is a vector quantity.
  • Its SI unit is Newton and the CGS unit is Dyne.
  • 1 newton = 105 dyne
