Electromagnetic Spectrum Quotes

As far as the radio waves part of the spectrum, we can do these adequately from the ground because the atmosphere is basically transparent to our radio waves.

This change in the conception of reality is the most profound and the most fruitful that physics has experienced since the time of Newton. Refering to James Clerk Maxwell's contributions to physics.

Our television transmitters leak out from the Earth. And actually, there's a sphere surrounding the Earth from the earliest television signals, maybe 70 years ago, that's going out one light year per year. But it's really weak.

For in 1900 all electromagnetic radiation of longer wavelengths was already known at least to the extent that one could not seek in it the more striking characteristics of X-rays such as, for example, the strong penetrating power.

We have all kinds of limitations as human beings. I mean we can't see the whole electromagnetic spectrum, we can't see the very small, we can't see the very far. So we compensate for these short comings with technological scaffoldings. The microscope allows us to extend our vision into the microsphere. The telescope allows us to extend our vision into the macrosphere, the Hubble Space Telescope extends our optic nerve into space, and it allows us to mainline space and time through our optic nerve.

Science works its miracles by turning its enterprise into a kind of parlor game confined to the category matter and energy.

One scientific epoch ended and another began with James Clerk Maxwell.

Light is therefore color.

Broadly speaking, the discovery of X-rays has increased the keenness of our vision ten thousand times, and we can now 'see' the individual atoms and molecules.

Since we can produce all types of light by means of hot bodies, we can ascribe, to the radiation in thermal equilibrium with hot bodies, the temperature of these bodies, and thus every radiation, even that issuing from a phosphorescent body, has a certain temperature for every colour.

I have not had a moment's peace or happiness in respect to electromagnetic theory since November 28, 1846. All this time I have been liable to fits of ether dipsomania, kept away at intervals only by rigorous abstention from thought on the subject.

The content of physics is the concern of physicists, its effect the concern of all men.

In 1959 the University recognized our work by appointing me to a new Chair of Radio Astronomy.

Eighty percent of the information we receive comes through our eyes. And if you compare light energy to musical scales, it would only be one octave that the naked eye can see, which is right in the middle.

Along a series of lines running from longer to shorter wavelengths the effect of the electric field becomes greater as the serial numbers increase - that is, as the wavelength decreases.

There is no greater mystery to me than that of light traveling through darkness.

Everything is made of light

There is no doubt that I, also, had long been aware of the problem, i.e. producing X-ray interferences, before the inherent difficulties had finally been surmounted.

I was very eager to produce an oscillator for short waves. I was doing science with microwaves, and I would get down to a few millimetres in wavelength, but I wanted to get shorter wavelengths; I wanted to get into the infra-red because I saw there was a lot more to be done there.

There were several possible solutions of the difficulty of classical electrodynamics, any one of which might serve as a good starting point to the solution of the difficulties of quantum electrodynamics.

Electrical science has disclosed to us the more intimate relation existing between widely different forces and phenomena and has thus led us to a more complete comprehension of Nature and its many manifestations to our senses.

Even on television, the wavelengths that you use, they have to be distributed between countries.

Violet has the shortest wavelength of the spectrum. Behind it, the invisible ultraviolet. Roses are Red, Violets are Blue. Poor violet, violated for a rhyme.

I am busy just now again on Electro-Magnetism and think I have got hold of a good thing but can't say; it may be a weed instead of a fish that after all my labour I may at last pull up.

A radiometer is a device for measuring the intensity of radiation. A microwave radiometer consists of a filter to select a desired band of frequencies followed by a detector which produces an output voltage proportional to its input power.
