some microwaves get absorbed and heat us up• Radio and Microwaves are at the low energy end• So electricity and magnetism are linked in an ongoing dance | Here is the full electromagnetic spectrum: Higher frequency rate of vibration has more energy and shorter wavelength |
---|---|
radio waves pass through our bodies• Energy and Ionization Gamma rays, x-rays, and some ultraviolet waves have such high energy that they are "ionizing," meaning they can knock electrons out of atoms |
So telescopes like the NuSTAR X-ray telescope have to be in orbit.
13[…] Herschel decided to measure the temperature just beyond the red of the spectrum in a region where no sunlight was visible | |
---|---|
Each photon has a wavelength So it is like a particle and also like a wave | Rays X-rays and gamma rays at the high energy end To remember the energy and danger levels, think "Radio is low, but rays are like razors" |
Speed of Light Electromagnetic waves travel at the "Speed of Light" at almost 300,000,000 meters per second to be exact: 299,792,458 meters per second in a vacuum.
