Its also a satellite for cell phones and televisions. • Infuriate rays – it detects body rays. • Invisible light - like the sun is invisible light, lamp light. • UV rays – are invisible rays from the sun. • X rays – humans use to see bones. • Gama rays- is the smallest wavelength with the most energy. We use it to kill living cells and for medicine.
