Electromagnetic radiation is a form of power that is typically recognized as light. Normally speaking, we say that light travels in waves, and all electromagnetic radiation travels at the same speed which is about 3.0 * 108 meters per second via a vacuum. We speak to this the "rate of light"; nothing deserve to move much faster than the rate of light.

A wavesize is one cycle of a wave, and also we meacertain it as the distance in between any two consecutive peaks of a wave.The peak is the highest possible allude of the wave, and the trough is the lowest allude of the wave.

Frequency

So once we talk about light traveling in waves, we have the right to additionally talk around frequency, or the number of wavelengths that passa details point in a provided length of time. We generally meacertain this as the number of wavesize cycles that pass per second. The units for this measurement are Hertz (hz).So, if the wavelength of a light wave is shorter, that suggests that the frequency will certainly be better bereason one cycle have the right to pass in a much shorter amount of time. This implies that more cycles can pass by the set suggest in 1 second. Likewise, a light wave that has a much longer wavesize will have a lower frequency bereason each cycle takes a much longer time to finish.

This is an example of a much shorter wavelength. Like we sassist earlier, if you were an observer standing on the babsence line, and you were so quick that you might count the variety of wave peaks that passed you in one second, you would certainly discover that the number of wave peaks that you counted would be better than a much longer wavelength. This is an example of a longer wavelength. Suppose you put yourself on the line again and you start clocking the variety of wave peaks that pass you. Wait a minute, not virtually so many wave peaks have gone by in one second favor prior to with the shorter wavesize. That indicates that longer wavelengths have a lower frequency.
Conclusion: a much longer wavelength means a lower frequency, and a shorter wavelength implies a greater frequency!

How does this relate to the Electromagnetic Spectrum?

Like we said before, light can be identified by its wavesize. For instance, the human eye deserve to detect light at wavelengths between 400 to 900 nanometers. That is why we call this part of the electromagnetic spectrum visible light. Light waves with shorter wavelengths (and better frequencies) also have actually more energy, so kinds of light prefer gamma rays, X-rays, and also ultraviolet light are even more energetic than visible light, and infrared, microwaves, and radio waves are much less energetic than the light in the visible spectrum.To go earlier to the electromagnetic spectrum.
