I have just watched a Kurzgesagt video about light, in the video it was stated that gamma rays are smaller than hydrogen atoms, and that Radio waves can be as large as asteroids, but I don't understand the link... I Know that gamma rays have higher frequency than radio waves (and vice versa for wavelength) but does this make the size of the whole wave larger, why can't radio waves detect small microbes as well as gamma rays? I would agree with this only if you prove to me that the vertical distance in a radio wave is larger than the vertical distance of a gamma rays. (vertical distance between maximum and minimum points in the wave) If you feel lost just respond to this question, why can't electromagnetic waves detect objects which are smaller than their wavelength (try proving either by formulas or by physics through an analogous experiment and thanks in advance)
Electromagnetic waves have no "vertical distance" ascribed to them, the way water waves do; this analogy doesn't work with with EM radiation. The peaks in the EM wave are where the intensity of the electric or magnetic field is at a maximum, depending on how you measure the field.
The basic idea here is that all types of EM radiation possess both frequency and wavelength, with high frequencies corresponding to short wavelengths and low frequencies corresponding to long wavelengths. The equation is
(frequency) = (speed of light)/(wavelength)
so, for example, an EM wave with a frequency of 30 megahertz has a wavelength of about 10 meters.
In general, an EM wave has little effect on a material object if its wavelength is longer than the physical dimensions of that object, which is why you cannot use a light microscope to look at individual atoms or molecules and why a metal wall 30 meters across acts like a mirror for a 30 megahertz radio signal.
If the vertical distance is the wave amplitude, it is not the thing to compare because the amplitude determines the wave intensity rather than the wavelength.
A wavelength is some characteristic of the EMF, but it is not very speaking either. For example, one photon of a (nearly) certain frequency contains many-many wavelengths.
Small objects may emit and absorb long waves, remember the heat radiation/absorption.
