# What is the amplitude the electric field? ## What is the amplitude the electric field?

In electromagnetic waves, the ampltude is the maximum magnetic field strength. (See Figure 1.). (See Figure 1.)

## How do you determine the amplitude of a wave?

Amplitude can be calculated by looking at a wave graph and measuring its height from the resting point. Amplitude refers to the strength or intensity a wave. The amplitude is a measure of how loud a sound wave is.

How do I calculate amplitude?

The Amplitude refers to the height between the center line and the peak (or the trough). You can also measure the height between the highest and lowest points, then divide it by 2.

### What does it mean when a wave amplitude increases?

A sound is perceived louder if its amplitude is greater, and less if it’s smaller. The amount of energy a wave carries is determined by its amplitude. A large amplitude wave is one that carries more energy than a smaller wave with a lower amplitude.

Does energy depend on amplitude?

The amplitude and frequency of a wave determine the amount of energy it contains. The amplitude determines how high the wave lifts the seagull and how much potential energy it generates. Both the frequency and the amplitude determine the energy of the wave.

#### How can you change the amplitude of the wave?

Amplitude refers to the size of a wave or the distance between its peak (or its trough) in vertical space. You can increase the amplitude by making more motions. Frequency is another property. It is the distance between one peak/trough and the next. You could shale the rope more quickly to increase frequency.

#### Does amplitude affect volume?

The amplitude of a soundwave determines its volume or loudness. An amplitude that is larger or smaller will indicate a louder sound. The sensitivity of your ear also determines the loudness of a sound.

What is the amplitude of a photon?

Photons lack amplitude. Photons lack amplitude. They possess energy. The wavelength of associated radiation is an indicator of how much energy a photon has. High-frequency waves are therefore known to produce high-energy photons. A higher wave amplitude at the exact same frequency equals more photons of the same energy.

## Does higher frequency mean higher intensity?

If the intensity of a wave depends on its frequency, then why does sound level not depend on frequency? i.e. A higher frequency means a higher level of intensity and a higher level of sound. Frequency does not appear to affect the loudness of a sound. However, the equation above shows that intensity DOES depend upon frequency.

## Do all photons have the same amplitude?

Photons have no amplitude. All photons with equal frequencies have the same energy. The energy of electromagnetic waves can vary in amplitude. This is because they contain different numbers of photons.
