When white light lite is dispersed by a prism a spectrum is obtained on a screen if you pass a beam of pure blue light through a prism what would you see on the screen?

We see different colours of light because of their different frequencies. White light is actually lots of different frequencies, you see a spectrum because when light diffracts (slows down and changes direction) each frequency diffracts by a different amount, some bend more than others. Because blue light is only one frequency it will not produce a spectrum, so all the light bends by the same ammount.

How come when you look through 2 magnifying glasses everything is upside down?
When we are looking through a magnifying glass from a position far away from the focus , a real image is formed which is inverted.This inverted image cannot be obtained on the screen.Hence we see the image upside down. However if we look through the magnifying glass at a position between the optical centre and focus a virtual,erect and magnified image will be formed.This can be obtained on the screen.
What is a natural phenomenon that exhibits a continuous spectrum?
A continuous spectrum is produced when white light passes through a prism or when hot gas is heated to incandescence. In either case the light is separated into its component colors based on their different wavelengths. All the colors of the visible spectrum from red to violet are present in the resulting continuous spectrum.When white light passes through a prism the individual wavelengths of light are bent at different angles separating the light into a spectrum. This is known as dispersion. The prism separates the wavelengths of light into visible colors with the shortest wavelength being the color red and the longest wavelength being the color violet.When hot gas is heated to incandescence the gas molecules become excited and emit light. The light produced is a continuous spectrum because all the wavelengths of visible light are present. The intensity of the emitted light varies with the wavelength with the shortest wavelength having the greatest intensity and the longest wavelength having the least intensity.
What electromagnetic spectrum is used for radio broadcasting?
Radio wave brings the information into the TV set from which the sound and pictureare reconstructed.Light wave carries the picture ("video") information from the screen to your eyes.
What can separate water?

An electron is sent through a screen with two slits The electron is not detectedwatched as it goes through the slits What slit or slits does the electron go through?
Crazily enough, both. The electron behaves like a wave in this case, not a particle.
Is the spectrum for the incandescent light a continuous spectrum or a line spectrum?
incandescent bulb is equivalent to white light, i.e it has all the seven wavelengths of light. therefore when passed through a prism it is disperses into all the seven wavelengths WITHOUT ANY SPACES OR BOUNDARIES and are obtained on the screen as a CONTINUOUS SPECTRUM.

How can you tell what colors make up white light?
The classical experiment consists in directing sunlight through a glass prism onto a screen. Light in: invisible. Light out (and displayed on screen): full spectrum of visible colors.

Plane mirrors do not create images that can be placed on a screen, only concave mirrors can.
Differences between output on a screen and a printer?
In some Microsoft programs, there is a screen font and a printer font. The text appears as the screen font while on the screen, but the printer receives the alloted text in the printer font. Hope that was useful. Also get rid of the 1 in front of the question.
