## What happens when amplitude is doubled?

The energy transported by a wave is directly proportional to the square of the amplitude. So whatever change occurs in the amplitude, the square of that effect impacts the energy. This means that a doubling of the amplitude results in a quadrupling of the energy.

## What happens to the loudness of sound if its amplitude is doubled?

Loudness of sound is directly proportional to the square of the amplitude. When amplitude is doubled, loudness becomes 4 times.

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. The amplitude increases with an increase in the frequency of a wave.

## What will happen to the loudness of the sound if amplitude of a wave is tripled?

Thus, when amplitude of the wave is tripled, the loudness increases nine times.

## What is the relationship between loudness and amplitude if amplitude is tripled by how much does loudness increase?

Loudness of sound is proportional to the square of amplitude. If the amplitude is tripled, the loudness increases by nine times.

## What amplitude means?

Amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path.

## Which of the following depends on amplitude?

Amplitude and sound are directly proportional. The amplitude of the wave determines the loudness of a sound wave. A larger amplitude means a loud sound while a smaller amplitude means a soft sound. If the amplitude is high then the sound will be louder and the sound will be feeble if the amplitude is low.

## Is proportional to the square of amplitude?

As defined in physics, the intensity of a wave is proportional to the square of its amplitude (A2 ∝ I). So that means that if we want to emulate the effect of a sound being twice as far away, (1/4 the intensity), we would need to multiply the amplitude by one-half.

## What is the relationship between pitch and frequency?

The sensation of a frequency is commonly referred to as the pitch of a sound. A high pitch sound corresponds to a high frequency sound wave and a low pitch sound corresponds to a low frequency sound wave.

## What is the Earth’s hertz frequency?

The Earth behaves like a gigantic electric circuit. Its electromagnetic field surrounds and protects all living things with a natural frequency pulsation of 7.83 hertz on average — the so-called “Schumann resonance,” named after physicist Dr. Winfried Otto Schumann, who predicted it mathematically in 1952.
