"Wifi signals emit non-ionic radiation or low energy which is almost the same as mobile phone signals, microwave, radio, and ultraviolet light." I have a couple problems with this. While you are correct with like 95% of this statement low frequency EMR is nothing like Ultraviolet, which is high frequency ionizing radiation. Infrared radiation and the entire spectrum of visible light lies between the two.[1] Wi-fi operates at between 2.4 and 5GHz[2] where as visible violet light (from solar radiation or a grow bulb for example) has a frequency of around 3PHz and extreme ultraviolet radiation is at around 30PHz[1]. For reference 1 PHz is 1,000,000GHz. Hopefully this helps illustrate how your statement comparing wifi EMR and UV was incorrect. Please try not to spread misinformation. Additionally its a good idea to link sources you use as references in your post to increase your credibility and transparency.
