What happens to a light wave when you increase the amplitude?

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 is the difference in the effect of increasing the intensity of the light on the photoelectric cell compared to increasing the frequency of the photons?\?

Summary. Based on the wave model of light, physicists predicted that increasing light amplitude would increase the kinetic energy of emitted photoelectrons, while increasing the frequency would increase measured current.

What happens to a light wave when you increase the frequency?

An increase in frequency produces a proportional decrease in the wavelength of light with a corresponding increase in the energy of the photons that make up the light. Thus as frequency increases (with a corresponding decrease in wavelength), the photon energy increases and visa versa.

How would you describe the difference between a high amplitude wave and a low amplitude wave?

The amplitude of a wave is related to the amount of energy it carries. A high amplitude wave carries a large amount of energy; a low amplitude wave carries a small amount of energy. The average amount of energy passing through a unit area per unit of time in a specified direction is called the intensity of the wave.

What is the relationship between intensity of light and amplitude?

In Physics, the relation between amplitude and intensity is that the intensity of the wave is directly proportional to the square of its amplitude.

How does increasing the frequency and intensity of light affect a photoelectric current?

If the frequency and the intensity of the incident radiation are fixed, the photoelectric current I increases with an increase in the positive voltage, as more and more electrons are directed onto the electrode. When no additional photoelectrons can be collected, the photoelectric current attains a saturation value.

Does an increase in the light intensity increase the kinetic energy of the photoelectrons?

When a photoelectric effect is observed, the number of electrons ejected is proportional to the intensity of the incident light. The maximum kinetic energy of the photoelectrons increases with higher frequency light.

What happens when you increase amplitude?

The sound is perceived as louder if the amplitude increases, and softer if the amplitude decreases. As the amplitude of the sound wave increases, the intensity of the sound increases. Sounds with higher intensities are perceived to be louder.
