The discovery that stars emit energy across the entire electromagnetic spectrum led to what innovations?
You might be referring to radio astronomy.
Sunlight is a form of electromagnetic energy?
Sunlight contains a wide range of the electromagnetic spectrum. Newton found that by using a prism to spread the spectrum of the sun across a wall He could observe the colors of light and with a thermometer even detect infrared light where there was no visible light at the red end of the colors. /\ | | That wasn't the question?
What are the values of the product of frequency and wavelength in the different spectra?
Frequency = cycles/secondWavelength = distance/cycleFrequency * Wavelength = cycles/second * distance/cycle = distance/second = speed of propagation of that type of waveFor electrometric radiation in a vacuum this will be a constant across the entire spectrum, but not when the radiation is in a material medium. For other types of waves this may be constant or vary in complex ways across the spectrum.
What is a visible ray?
"Visible" electromagnetic radiation is radiation with wavelengths between roughly 390 to 750 nanometers. (0.000350 to 0.000750 millimeters) -- If electromagnetic radiation with a wavelength in this range enters your eye, you know it, because the retina of your eye responds to these wavelengths. -- If radiation enters your eye but its wavelength is not in this range, you don't notice it. -- If there is radiation in the neighborhood with wavelength in this range but it doesn't enter your eye, then you don't notice it. (If a flashlight shines a spot on the wall across the room, you don't see the shaft of light on its way across the room. You see it only after the light hits the wall and some of it bounces off the wall and into your eyes. )
Explain the effects on frequency wavelength and energy as you move across the spectrum?
E=hv where E=energy v=frequency v=Planck's constant as you move further towards the xray side, frequency and energy increase.
How does radiation change across the electromagnetic spectrum?
The amount of radiation changes across the spectrum.
What spectrum does the sun emit?
The Sun emits radiation across almost the entire electromagnetic spectrum.
The discovery that stars emit energy across the entire electromagnetic spectrum lead to what invention?
spectroscope!
What is color absorption?
Absorption spectroscopy refers to spectroscopic techniques that measure the absorption of radiation, as a function of frequency or wavelength, due to its interaction with a sample. The sample absorbs energy, i.e., photons, from the radiating field. The intensity of the absorption varies as a function of frequency, and this variation is the absorption spectrum. Absorption spectroscopy is performed across the electromagnetic spectrum.
What is the elctromagnetic background?
The constant noise in the electromagnetic spectrum, caused by various sources, from lightning on Jupiter to someone using an electric razor. There is electromagnetic energy present across the frequency spectrum, which is called 'noise' because it carries no intelligence that we can discern.
The discovery that stars emit energy across the entire electromagnetic spectrum led to what innovations?

What advantages in structural biology are gained by the synchrotron?
A small part of the electromagnetic spectrum which ranges from the long wavelengths-radio waves, microwaves and infrared through the visible spectrum to the short wavelengths of ultraviolet light, X-Rays and gamma rays. Synchrotron light is unique in its intensity and brilliance and it can be generated across the range of the electromagnetic spectrum.
Why do astronomers use frequencies when investigating the universe?
It is because stars and other cosmic objects, radiate energy across the whole of the electromagnetic spectrum.

How does energy associated with waves change as wavelength changes?
Using this equation will help you understand what is going on: E=hc/wavelength h and c are constants. As wavelength increases, energy decreases. This is why UV radiation (which has a very small wavelength) has more energy than visible radiation, and this is also why UV radiation causes damage to living things
What is the Energy that travels across distances in the form of electromagnetic waves?
Energy transfered in the form of electromagnetic waves is classified according to wavelength of the radiation. Radio waves, microwaves, infrared radiation, visible light, ultraviolet light, X-rays and gamma rays are all forms of electromagnetic radiation.
