What spectrum is white light?

visible spectrum
This visible portion of the electromagnetic spectrum is called the visible spectrum. When you mix all of the wavelengths of the visible spectrum, you get white light.

What type of light gives a continuous spectrum?

incandescent light bulb
An incandescent light bulb produces a continuous spectrum because the source of the light is a metal filament (wire).

What is continuous spectrum?

: a spectrum (as of light emitted by a white-hot lamp filament) having no apparent breaks or gaps throughout its wavelength range.

What is an example of a continuous spectrum?

Continuous Spectrum. A rainbow is an example of a continuous spectrum. Here, the colors displayed are within the visible spectrum (between 380-760 nm). Light in this wavelength range is visible to the naked eye.

What are two sources of white light?

For example: the stars and Sun are the sources of white light. The obvious source of white light in the solar system is the Sun. The white LED’s and fluorescent light bulb producing white light is an artificial source of light.

Where is white light on the spectrum?

In simple terms, electromagnetic radiation of all the frequencies in the visible range of the spectrum, appearing white to the eye is called white light. Visible light or white light comes above infrared rays.

What can we learn from a continuous spectrum?

A continuous spectrum contains many different colors, or wavelengths, with no gaps. Perfectly white light shined through a prism causes dispersion of the light, and we see a rainbow. Looking at absorption and emission spectra can tell you what elements are present in stars like the sun and other gasses.

Is street light continuous spectrum?

Unlike the continuous spectrum emitted by blackbody radiators, the light given off by atoms in a gaseous discharge is characterized by its discreet nature. Using street lamps for the light sources, bright atomic spectra of mercury or sodium are projected onto a screen.

What causes continuous spectrum?

Continuous spectra (also called thermal or blackbody spectra) arise from dense gases or solid objects which radiate heat. They emit radiation over a broad range of wavelengths, thus the spectra appear smooth and continuous.

What do you mean by white light?

White light is light such as sunlight that contains all the colors of the visible spectrum in roughly equal amounts.

What is white light Give source of white light?

the Sun
The obvious source of white light in the solar system is the Sun. The white LED’s and fluorescent light bulb producing white light is an artificial source of light.

What is the difference between a continuous spectrum and line spectrum?

There is a continuous and line spectrum. A continuous spectrum consists of all wavelengths within a certain range. This spectrum looks like a rainbow. In contrast, a line spectrum only consists of a few wavelengths.
