What’s the point of the different frequencies for programs? What’s the difference between a frequency of 50 and 900?

The best answer I can give you is the definition followed by some examples I hope puts everything into perspective.

First, a frequency is just the rate at which a vibration occurs that constitutes a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light), usually measured per second.
So for your selected example frequencies, one is vibrating 50 times a second the other 900 times a second.

Now to put that into terms you can relate to.

When you are listening to music, each note has a frequency and you register this as different pitches with your ears.

50 Hz would be a nice deep base note.

900 Hz would be a slightly off-key A5 note (which has a frequency of 880). It would be in the higher pitch range, like the tone you hear before an emergency broadcast message.

All frequencies we hear are in the sound range, which is from 20 Hz to 20,000 Hz.

Another example I can give you for how we use frequencies in our daily lives.

FM radio stations all broadcasted on a specific frequency. When you tune into 89.9 FM, you are listening to audio encoded onto a frequency of 89.9 MHz (millions of hertz). AM stations are in kHz, so when you tune into 910 AM, the audio is encoded onto a frequency of 910 kHz (thousands of hertz). We use these higher frequencies because we can’t hear them as they fly through the air.
Microwave ovens use a frequency roughly around 2.45 gigahertz (GHz). This frequency range can resonate with water which causes water to vibrate. Vibrations cause heat through friction, which is how it heats up the food.
As for their use on the scalar field as a modulator (as in the case of using a generator running a program), different frequencies used will change the rate at which the scalar field is turned on and off. This has a direct effect of changing what frequencies are generated in the scalar field. All frequencies generated will be centered around the frequency used to tune.

The primary use for a frequency on the scalar boxes is the tuning frequency. This frequency allows for the creation of the scalar field in the first place. Wrong frequency, no scalar field.

The primary goal in generating a frequency in Rife application, is to use a frequency that resonates with a pathogen which will cause it to vibrate to devitalization.
