what is the main difference between continuous spectrum and atomic emission spectrum?
11532
Continuous spectrum: a spectrum that has all wavelengths with no gaps over a wide range. Solids at high temperatures, like the filament of an electric lamp, produce continuous spectra. Emission spectrum: when an electron in an excited state moves to a lower energy level, it emits a certain amount of energy as photons.

Infrared is slightly lower energy than red light, and it's outside of the visible light spectrum. Ultraviolet light, on the other hand, is on the other side. ... Basically, Infrared light is a longer wavelength than what we can see, and Ultraviolet is a shorter wavelngth than what we can see.

As adjectives the difference between perpetual and continuous. is that perpetual is lasting forever, or for an indefinitely long time while continuous is without break, cessation, or interruption; without intervening time.

Emitted light is from an object that is generating the light it gives off. ... Reflected light does not create its own light. Light from another source bounces off of objects, which is how we see it. Generally speaking, if the object is not safe to look at, it is emitting light, like the sun or a light bulb filament.

Visible Color Spectrum Gamma rays (the size of a nucleus) are more powerful than A.M. radio waves (the size of a village) Violet at 400 mµ is stronger than red at 700 mµ. Purple! Find out more about violet (purple), the most powerful color of the rainbow.

While IR represents electromagnetic radiation with wavelengths longer than those of visible light, UV represents wavelengths shorter than visible light. ... The UV radiation, on the other hand, covers the wavelength range of 400 nm (violet edge) to 10 nm.

Non-ionizing radiation is longer wavelength/lower frequency lower energy. While ionizing radiation is short wavelength/high frequency higher energy. Ionizing Radiation has sufficient energy to produce ions in matter at the molecular level.

Emitted light is from an object that is generating the light it gives off. Very hot objects give off light. ... Reflected light does not create its own light. Light from another source bounces off of objects, which is how we see it.

The visible light spectrum is the section of the electromagnetic radiation spectrum that is visible to the human eye. Essentially, that equates to the colors the human eye can see. It ranges in wavelength from approximately 400 nanometers (4 x 10 -7 m, which is violet) to 700 nm (7 x 10-7 m, which is red).

Atoms emit light at certain characteristic frequencies. So one gets lines on the screen corresponding to those frequencies, in their spectra. ... Hence, in general 'spectrum' refers to the whole range of wavelengths i.e it covers the entire domain of all wavelengths. Whereas, a 'band' is a specific range in the spectrum.

The difference between Rainbow and Spectrum. When used as nouns, rainbow means a multicoloured arch in the sky, produced by prismatic refraction of light within droplets of rain in the air, whereas spectrum means a range. ... Rainbow is also adjective with the meaning: multicolored.

Definition of ultraviolet spectrum. : a spectrum of ultraviolet radiation characterized by short wavelengths and high quantum energies as compared to visible light.

Shortwave radiation (visible light) contains a lot of energy; longwave radiation (infrared light) contains less energy than shortwave radiation (shortwave radiation has a shorter wavelength than longwave radation). ... The ground heats up and re-emits energy as longwave radiation in the form of infrared rays.

Principles of operation A fluorescent lamp generates light from collisions in a hot gas ('plasma') of free accelerated electrons with atoms– typically mercury – in which electrons are bumped up to higher energy levels and then fall back while emitting at two UV emission lines (254 nm and 185 nm).

The Visible Spectrum White light is visible light, and it contains all the colors of the rainbow, from red to violet. The range of visible wavelengths is 400 to 700 nanometers. Ultraviolet light is the radiation from the sun that causes a sunburn when you have been outside too long on a sunny day.

One of the most important characteristics of these spectra is that they are discrete. By this we mean that only certain wavelengths, and hence frequencies, are emitted. ... If frequency and energy are associated as ΔE = hf, the energies of the electrons in the emitting atoms and molecules are quantized.

The basic difference between the two is that the grating spectrum is due to diffraction and dispersion spectrum is due to dispersion. We can hardly get higher order spectrum peaks in dispersion spectrum(only of order 1) but in grating spectrum we get higher order peaks(we can see of order 2 too).
