X-ray
the mission was to find white dwarfs a category of stars
By creating an xray using sound waves.
Sound waves need a medium to propagate. Light-waves and other electromagnetic wave (radio, xray) do not.
Mainly visual and radio. But there are Xray, UV and IR.
Energy that is radiated in a wave such as radio waves, white light, uv light and xray.
Electrons impact at high velocity on a tungsten anode. The tungsten emits the X-Rays, which are the electromagnetic waves.
star like a sun big but not really starlike and xray gives off radio waves ......
dolphins kind of have xray vision they use sound waves and feel what comes back
An X-ray proton. This is so because the x-ray has much higher frequency and shorter waves.

There is no antonym. An xray is a wavelength. There is no opposite.
Light waves and 'radio' waves (i.e. infra red, UV, xray, etc.) At one time it was thought they did have a medium. A sort of 'gelatin' that went throughout the universe. The called 'the ether'. You see the term used a lot in radio magazines of the 1910s and 1920s.
