What is the amplitude of a visible wave?

The amplitude of a. wave is the height of a wave as measured from the highest point on the wave (peak or crest) to the lowest. point on the wave (trough). Wavelength refers to the length of a wave from one peak to the next.

What is the amplitude and frequency of visible light?

Visible light falls in the range of the EM spectrum between infrared (IR) and ultraviolet (UV). It has frequencies of about 4 × 1014 to 8 × 1014 cycles per second, or hertz (Hz) and wavelengths of about 740 nanometers (nm) or 2.9 × 10−5 inches, to 380 nm (1.5 × 10−5 inches).

What is the amplitude of a light?

the maximum deviation of a wave of light from its median intensity. The greater the amplitude of a light wave, the brighter it appears.

How do you find amplitude of light?

If you know the intensity, then the amplitude can be found using this formula I=1/2*pvw*A^2 where p is density, v, w is angular velocity, v is speed of wave. Hence, if you measure the intensity in a a unit area, (W m^-2), you can find the amplitude inversely solving.

Does light have a fixed amplitude?

Intensity of light refers to the number of photons and the energy of each is based on its frequency. Brightness of light corresponds to amplitude. Amplitude of light from two light bulbs are larger than that from one light bulb. Amplitude of light from each bulb is additive.

What is the amplitude of a gamma ray?

Gamma rays fall in the range of the EM spectrum above soft X-rays. Gamma rays have frequencies greater than about 10^19 cycles per second, or hertz (Hz), and wavelengths of less than 100 picometers (pm), or 4 x 10^9 inches.

What is the amplitude of ultraviolet light?

Ultraviolet radiation lies between visible light and X-rays along the electromagnetic spectrum. UV “light” spans a range of wavelengths between about 10 and 400 nanometers. The wavelength of violet light is around 400 nanometers (or 4,000 Å).

What is wavelength and amplitude?

AMPLITUDE AND WAVELENGTH The amplitude of a wave is the height of a wave as measured from the highest point on the wave (peak or crest) to the lowest point on the wave (trough). Wavelength refers to the length of a wave from one peak to the next.

Does a photon have amplitude?

If you use photons, you don’t have to worry about amplitudes, energy is calculated using Photon Energy, and this reference gives you the math. But amplitude is more a wave related concept than any application to particles.

Which wave has highest amplitude?

Gamma rays
Gamma rays has the greatest amplitude among all electromagnetic waves.
