longer.
As you move left to right on the electro magnetic spectrum the wavelength becomes longer.
As you move from left to right across the electromagnetic spectrum, the frequency increases, the wavelength decreases, and the energy of the electromagnetic waves increases. This means that on the left side, you have low-frequency, long-wavelength, low-energy waves like radio waves, while on the right side, you have high-frequency, short-wavelength, high-energy waves like gamma rays.

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?
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.
"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. )
The amount of radiation changes across the spectrum.
The Sun emits radiation across almost the entire electromagnetic spectrum.

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.
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.

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.
It is because stars and other cosmic objects, radiate energy across the whole of the electromagnetic spectrum.

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
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.
