Welcome to Wikipedia! I'm Chetvorno. Thanks for your edit to radio frequency. Someone reverted it not because they disagreed with you but because your information didn't include a source. On Wikipedia any content that people are likely to question should have a link to a WP:reliable source that supports the data, see WP:Verifiability. You can do this by including an WP:citation to the NASA website where you got the information, at the end of the sentence. WP:Citing sources gives instructions.

You can create your own citation by using the tags, like this:

Or you can use a WP:citation template that has fields for the information like this Either of these methods adds a citation number to the end of the sentence, like this and puts the source information into the "References" section at the end of the article:
 * Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency range from around $3 kHz$ to around $300 GHz$.

If you click on the number you can see the link to NASA's website where the information is. This satisfies the requirement of citing a reliable source for your content, so (hopefully) no one will revert your edit on the grounds of lacking verifiability.

If you have any other questions about Wikipedia, or I can help at all, please leave me a message on my Talk page: User Talk:Chetvorno. Cheers! --ChetvornoTALK 00:59, 1 August 2021 (UTC)
