What can a diffraction grating be used for?
measuring wavelengths of light
How are wavelengths of light detected?
Spectroscopy originated through the study of visible light dispersed by a prism according to its wavelength. An instrument called a spectrometer is used in spectroscopy for producing spectral lines and measuring their wavelengths and intensities.
Wavelengths of violet light compared to wavelengths of ultraviolet light?
Violet light has longer wavelengths.
How is the refractive index used?
The refractive index measures the speed of light and wavelengths. Measuring the refractive index of an object by wavelengths is very confusing to most people. Many scientists have got it figured out.
What is the separation of light into different wavelengths?
It means the wavelengths are separated. White light, for example, is actually a mixture of different wavelengths.
What can a diffraction grating be used for?
measuring wavelengths of light
Why is using a light year useful for measuring stars?
Because the distance between stars is so great.
Is angstrom the unit of time?
No, the angstrom is a unit of distance. Specifically 0.1 nanometer. It is a very convenient unit for measuring the wavelengths of various colors of visible light.
Which equipment is most useful when measuring two enviromental changes?
A thermometer and light meter are the most useful when measuring two environmental changes.
What two wavelengths of light are least and most useful to photosynthesis?
Red light and blue light.Photosynthesis is not efficient under green light.
How are wavelengths of light detected?
Spectroscopy originated through the study of visible light dispersed by a prism according to its wavelength. An instrument called a spectrometer is used in spectroscopy for producing spectral lines and measuring their wavelengths and intensities.
Which these is a term for measuring distance in space?
light-year(:
Why is spectroscope a useful qualitative analysis tool?
Spectroscope is a useful qualitative analysis tool because is it can analyze wavelengths what humans can't see especially infrared and ultraviolet radiation. Also since light has a different color of wavelengths; Scientist can find useful information such as chemical elements present at the source of the light.
Wavelengths of violet light compared to wavelengths of ultraviolet light?
Violet light has longer wavelengths.
Is all of the electricity used to light a light bulb useful light?
No. Part of the energy is wasted, mainly as heat.
How is the refractive index used?
The refractive index measures the speed of light and wavelengths. Measuring the refractive index of an object by wavelengths is very confusing to most people. Many scientists have got it figured out.
