What thing cannot be viewed in compound microscope?
Viruses. They are smaller than the average wavelength of light and as such are not viewable unless an electron microscope is used.
What is the relationship between intensity and frequency?
I assume you are asking in regard to the photoelectric effect. The intensity of the photons can be viewed as the brightness of the light. However, the frequency is the number of wavelengths that pass a certain point in a second. The frequency is also used to determine the energy of the photon (E=hf).
How objects look different when viewed through the light microscope?
Objects viewed through a light microscope look a lot bigger.
Why can you see color when you cannot see a light wave?
Light waves are an electromagnetic radiation ranging in and wavelength. Only the wavelengths in between about 4,000 (violet) to about 7,700 (red) angstroms can be perceived by the human eye and is called visible light. The wave itself is too fast and too small to be viewed in an isolated manner. However, all light perceived by the Human eye is a light wave.
Why his fraunhofer diffraction single slit?
AnswerIn optics, the Fraunhofer diffraction equation is used to model the diffraction of waves when the diffraction pattern is viewed at a long distance from the diffracting object, and also when it is viewed at the focal plane of an imaging lens.In contrast, the diffraction pattern created near the object, in the near field region, is given by the Fresnel diffraction equation.The equation was named in honor of Joseph von Fraunhofer although he was not actually involved in the development of the theory.When the distance between the aperture and the plane in which the pattern is observed is large enough that the difference in phase between the light from the extremes of the aperture is much less than the wavelength, then individual contributions can be treated as though they are parallel. This is often known as the far field and is defined as being located at a distance which is significantly greater than W2/λ, where λ is the wavelength and W is the largest dimension in the aperture. The Fraunhofer equation can be used to model the diffraction in this case.Refer to links below for more information
When is Andromeda best viewed?
fall
What season is Andromeda best viewed in?
summer
Is Andromeda viewed northern or southern hepmisphere?
Northern.
What month can you see Andromeda the best?
The Andromeda constellation is best viewed at 21:00 during the month of November.
When was the Andromeda Galaxy discovered?
The Andromeda Galaxy is one of the few galaxies that is observable with the naked eye. Because of this, it cannot be said to be "discovered" as it has obviously been viewed by "man" since the earliest times.
How do they know that Andromeda is out there?
At an apparent magnitude of 3.4, the Andromeda Galaxy is one of the brightest Messier objects, making it visible to the naked eye on moonless nights even when viewed from areas with moderate light pollution.
When Is the constellation Andromeda visible?
In the Northern Hemisphere from June through February
Who changed the way humans viewed the universe?
Gallileo
What is the present idea about the nature of light?
well, right now it is believed that light travels in waves and is made up of massless particles called photons. these waves propagate at a constant speed, 3*10^8 m/s. Nothing can travel faster than this speed and nothing can travel the speed of light if it is not massless (so sorry, no hyperspace travel yet) while light always travels at the same speed, the frequency and wavelength of these propagating waves are not always the same. In the visible spectrum, the highest frequency waves are viewed as purple and the lowest frequency waves are red. The faster the frequency, the more energetic the wave. the frequency, wavelength, and speed of light are related to each other by this equation: speed of light=wavelength*frequency when dealing with the electromagnetic spectrum it is often easier to refer to light as electromagnetic radiation, especially when dealing with very high and very low frequencies that result in infrared, ultraviolet, radio, x-ray, etc. there is a lot of information out there about light, I'm just scratching the surface :-)
What document changed the way Americans viewed slavery?
the Declaration of Independence.
Which innovation changed the way people viewed movies in the 1990s?
DVDs
How did advertisers create markets?
Advertising changed the way people viewed products, making them more desirable.
